In the language of cladistics, the 50 unique characters are apomorphies which prove that mammals are a clade descended from a common ancestor.

Main groups
All mammals feed milk to their young, and protect and look after them.

The vast majority of mammal species give birth to live young, these are the placental mammals, most of which are classified as Eutheria and a small number are classified as marsupials.

Marsupials are mammals with pouches to carry young in, like the kangaroo.

There are only five species (the monotreme mammals) that lay eggs, the duck-billed platypus Ornithorhynchus, and four species of spiny anteater Echidna. The monotremes are confined to Australia and New Guinea, and are the sole survivors of an earlier group of mammals.
Modes of life
By number of species, mammals (with 5488 species), are not the most successful vertebrates. Birds, with about 10,000 species have nearly twice as many, and reptiles have just as many as birds. Fish have even more species. There are 27,000 species of fish, of which nearly 26,000 are bony fish.

Despite this, many zoologists do regard mammals as a successful group of animals. One reason is that they are successful in all habitats on Earth. In the air, in the water, in forests, in the colder regions of the world, and above all on grasslands, where they are outstandingly successful.

In the air, the bats (Chiroptera) are the mammalian order with the most species. They 'own' the nighttime, since birds are largely diurnal (daytime) animals. Bats are hugely successful, mostly as nighttime predators of insects.

Seagoing mammals, the Cetacea and the pinnipeds, are very successful and significant predators. This includes the whales, seals, walrus, dolphins and others.
The terrestrial mammals are fewer in number of species than lizards, but they are huge in individual numbers, and far more important in the life of the terrestrial biomes. Their ability to move from place to place and adapt has made them a most effective group. Many mammals live in cold places. These mammals have thick hair or blubber to keep them warm. Others may live in rainforests. On land the rodents (rats, mice) are hugely successful, more common in numbers than any other mammals. Large mammals on land have been hunted to extinction in some parts of the world, but the ones which remain are now better protected.

Last, but certainly not least, are the primates. Their natural habitat, with few exceptions, are the forests. Most live in the trees, with hands that grasp, good colour vision, and intelligence. In the Pliocene period some moved out onto the savannas as grassland replaced forests. Mankind is the result of this shift into the savannas.
Taxonomy
The evolutionary relationships among land vertebrates is as follows:
Tetrapoda (land vertebrates)
Amphibia (lay eggs in water)
Amniota (lay cleidoic eggs)
Sauropsida (all true 'reptiles')
Synapsida (all 'mammal-like amniotes')
Pelycosauria
Therapsida (in particular, the Cynodontia)
Mammalia (bear live young; milk; raise their young etc.)

This sort of classification is not traditional, but it does reflect our knowledge of palaeontology and evolution.

Standardized textbook classification
A somewhat standardized classification system has been adopted by most current mammalogy classroom textbooks. It is based on living animals. The following taxonomy of extant and recently extinct mammals is from Vaughan et al. 2000.

Class Mammalia
Subclass Prototheria: monotremes: platypuses and echidnas
Subclass Theria: live-bearing mammals
Infraclass Metatheria: marsupials
Infraclass Eutheria: placentals

List of living orders
Mammals can be divided in a number of orders:
 Monotremes (monotremata)
 Marsupials (marsupialia)
 Eutheria
 Superorder Xenarthra
 Order Pilosa
 Order Cingulata
 Superorder Afrotheria
 Order Proboscidea
 Superorder Laurasiatheria

 Order Carnivora
 Order Perissodactyla
 Order Artiodactyla
 Order Cetacea
 Superorder Euarchontoglires

 Order Primates

Debate on the meaning of "mammalia"
Because two quite different dates are given in the taxobox, an explanation is needed. Rowe defines mammals as "the taxon originating with the most recent common ancestor of extant (living) Monotremata and Theria". That puts the emphasis heavily on living mammals, where, as Rowe points out, the database of characters is extensive.
Kemp explains the problem with that approach: "If the definition of a mammal is based rigorously upon possession of all the characters of living mammals, then some fossil forms that are extremely mammalian in anatomy... are excluded".

"An altogether different perspective on defining Mammalia is based on traditional palaeobiological practice. An arbitrary decision is made about which characters to select as defining characters... Characters deemed appropriate are those reflecting the... fundamental mammalian biology. The essence of mammalian life is to be found in their endothermic temperature physiology, greatly enlarged brain, dentition capable of chewing food, highly agile, energetic locomotion, and so on. The organisms that achieved this grade of overall organisation are deemed to be Mammalia... Around the end of the Triassic period, about 205 mya, a number of fossils are found of very small animals that have [most] of the skeletal characters of modern mammals".
This difference in outlook explains the difference in the two dates given in the taxobox.

A number is a concept from mathematics, used to count or measure. Depending on the field of mathematics, where numbers are used, there are different definitions:
 People use symbols to represent numbers; they call them numerals. Common places where numerals are used are for labeling, as in telephone numbers, for ordering, as in serial numbers, or to put a unique identifier, as in an ISBN, a unique number that can identify a book.
 Cardinal numbers are used to measure how many items are in a set. For example, {A,B,C} has size "3".
 Ordinal numbers are used to specify a certain element in a set or sequence (first, second, third).

Numbers are also used for other things like counting. Numbers are used when things are measured. Numbers are used to study how the world works. Mathematics is a way to use numbers to learn about the world and make things. The study of the rules of the natural world is called science. The work that uses numbers to make things is called engineering.

Numbering methods
Numbering methods

Numbers for people 
There are different ways of giving symbols to numbers. These methods are called number systems. The most common number system that people use is the base ten number system. The base ten number system is also called the decimal number system. The base ten number system is common because people have ten fingers and ten toes. There are 10 different symbols (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) used in the base ten number system. These ten symbols are called digits.

A symbol for a number is made up of these ten digits. The position of the digits shows how big the number is. For example, the number 23 in the decimal number system really means (2 times 10) plus 3. Similarly, 101 means 1 times a hundred (=100) plus 0 times 10 (=0) plus 1 times 1 (=1).
Numbers for machines 
Another number system is more common for machines. The machine number system is called the binary number system. The binary number system is also called the base two number system. There are two different symbols (0 and 1) used in the base two number system. These two symbols are called bits.

A symbol for a binary number is made up of these two bit symbols. The position of the bit symbols shows how big the number is. For example, the number 10 in the binary number system really means 1 times 2 plus 0, and 101 means 1 times four (=4) plus 0 times two (=0) plus 1 times 1 (=1). The binary number 10 is the same as the decimal number 2. The binary number 101 is the same as the decimal number 5.

Names of numbers
Names of numbers 

English has special names for some of the numbers in the decimal number system that are "powers of ten". All of these power of ten numbers in the decimal number system use just the symbol "1" and the symbol "0". For example, ten tens is the same as ten times ten, or one hundred. In symbols, this is "10 × 10 = 100". Also, ten hundreds is the same as ten times one hundred, or one thousand. In symbols, this is "10 × 100 = 10 × 10 × 10 = 1000". Some other powers of ten also have special names:

 1 – one
 10 – ten
 100 – one hundred
 1,000 – one thousand
 1,000,000 – one million

When dealing with larger numbers than this, there are two different ways of naming the numbers in English. Under the "long scale", a new name is given every time the number is a million times larger than the last named number. It is also called the "British Standard". This scale used to be common in Britain, but is not often used in English-speaking countries today. It is still used in some other European nations.
Another scale is the "short scale", under which a new name is given every time a number is a thousand times larger than the last named number. This scale is a lot more common in most English-speaking nations today.

 1,000,000,000 – one billion (short scale), one milliard (long scale)
 1,000,000,000,000 – one trillion (short scale), one billion (long scale)
 1,000,000,000,000,000 – one quadrillion (short scale), one billiard (long scale)

Types of numbers

Natural numbers 
Natural numbers are the numbers which we normally use for counting: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Some people say that 0 is a natural number, too. The set of all natural numbers is written as .

Another name for these numbers is positive numbers. These numbers are sometimes written as +1 to show that they are different from the negative numbers. But not all positive numbers are natural (for example,  is positive, but not natural).
If 0 is called a natural number, then the natural numbers are the same as the whole numbers. If 0 is not called a natural number, then the natural numbers are the same as the counting numbers. So if the words "natural numbers" are not used, then there will be less confusion about whether zero is included or not. But unfortunately, some say that zero is not a whole number, while others say that whole numbers can be negative. "Positive integers" and "non-negative integers" are another way to include zero or exclude zero, but only if people know those words.

Negative numbers 
Negative numbers are numbers less than zero.

One way to think of negative numbers is to use a number line. We call one point on this line zero. Then we will label (write the name of) every position on the line by how far to the right of the zero point is. For example, the point one is one centimeter to the right, and the point two is two centimeters to the right.
However, the point one centimeter to the left of the zero point cannot be point one, since there is already a point called one. We therefore call this point minus one (−1, as it is one centimeter away but in the opposite direction).

A drawing of a number line is below.

All the normal operations of mathematics can be done with negative numbers:

 Adding a negative number to another is the same as taking away the positive number with the same numerals. For example, 5 + (−3) is the same as 5 − 3, and equals 2.
 Taking away a negative number from another is the same as adding the positive number with the same numerals. For example, 5 − (−3) is the same as 5 + 3, and equals 8.
 Multiplying two negative numbers together produces a positive number. For example, −5 times −3 is 15.
 Multiplying a negative number by a positive number, or multiply a positive number by a negative number, produces a negative result. For example, 5 times −3 is −15.
Since finding the square root of a negative number is impossible for real numbers (as negative times negative equals positive for real numbers), the square root of -1 is given a special name: i. This is also called the imaginary unit.

Integers 
Integers are all the natural numbers, all their opposites, and the number zero. Decimal numbers and fractions are not integers.

Rational numbers 
Rational numbers are numbers which can be written as fractions. This means that they can be written as a divided by b, where the numbers a and b are integers, and b is not zero.
Some rational numbers, such as 1/10, need a finite number of digits after the decimal point to write them in decimal form. The number one tenth is written in decimal form as 0.1. Numbers written with a finite decimal form are rational. Some rational numbers, such as 1/11, need an infinite number of digits after the decimal point to write them in decimal form. There is a repeating pattern to the digits following the decimal point. The number one eleventh is written in decimal form as 0.0909090909 ... .

A percentage could be called a rational number, because a percentage like 7% can be written as the fraction 7/100. It can also be written as the decimal 0.07. Sometimes, a ratio is considered as a rational number.

Irrational numbers 
Irrational numbers are numbers which cannot be written as a fraction, but do not have imaginary parts (explained later).
Irrational numbers often occur in geometry. For example, if we have a square which has sides of 1 meter, the distance between opposite corners is the square root of two, which equals 1.414213 ... . This is an irrational number. Mathematicians have proved that the square root of every natural number is either an integer or an irrational number.

One well-known irrational number is pi. This is the circumference (distance around) of a circle divided by its diameter (distance across). This number is the same for every circle. The number pi is approximately 3.1415926535 ... .

An irrational number cannot be fully written down in decimal form. It would have an infinite number of digits after the decimal point, and unlike 0.333333 ..., these digits would not repeat forever.
Real numbers 
Real numbers is a name for all the sets of numbers listed above:
 The rational numbers, including integers
 The irrational numbers
The real numbers form the real line. This is all the numbers that do not involve imaginary numbers.

Imaginary numbers 
Imaginary numbers are formed by real numbers multiplied by the number i. This number is the square root of minus one (−1).

There is no number in the real numbers which when squared, makes the number −1. Therefore, mathematicians invented a number. They called this number i, or the imaginary unit.

Imaginary numbers operate under the same rules as real numbers:
 The sum of two imaginary numbers is found by pulling out (factoring out) the i. For example, 2i + 3i = (2 + 3)i = 5i.
 The difference of two imaginary numbers is found similarly.  For example, 5i − 3i = (5 − 3)i = 2i.
 When multiplying two imaginary numbers, remember that i × i (i2) is −1.  For example, 5i × 3i = ( 5 × 3 ) × ( i × i ) = 15 × (−1) = −15.
Imaginary numbers were called imaginary because when they were first found, many mathematicians did not think they existed. The person who discovered imaginary numbers was Gerolamo Cardano in the 1500s. The first to use the words imaginary number was René Descartes. The first people to use these numbers were Leonard Euler and Carl Friedrich Gauss. Both lived in the 18th century.

Complex numbers 
Complex numbers are numbers which have two parts; a real part and an imaginary part. Every type of number written above is also a complex number.

Complex numbers are a more general form of numbers. The complex numbers can be drawn on a number plane. This is composed of a real number line, and an imaginary number line.

              |

All of normal mathematics can be done with complex numbers:
 To add two complex numbers, add the real and imaginary parts separately. For example, (2 + 3i) + (3 + 2i)  = (2 + 3) + (3 + 2)i= 5 + 5i.
 To subtract one complex number from another, subtract the real and imaginary parts separately. For example, (7 + 5i) − (3 + 3i) = (7 − 3) + (5 − 3)i = 4 + 2i.

To multiply two complex numbers is more complicated. It is easiest to describe in general terms, with two complex numbers a + bi and c + di.

For example, (4 + 5i) × (3 + 2i) = (4 × 3 − 5 × 2) + (4 × 2 + 5 × 3)i = (12 − 10) + (8 + 15)i = 2 + 23i.
Transcendental numbers 
A real or complex number is called a transcendental number if it can not be obtained as a result of an algebraic equation with integer coefficients.

Proving that a certain number is transcendental can be extremely difficult. Each transcendental number is also an irrational number. The first people to see that there were transcendental numbers were Gottfried Wilhelm Leibniz and Leonhard Euler. The first to actually prove there were transcendental numbers was Joseph Liouville. He did this in 1844.

Some well-known transcendental numbers include:
 e
 π
 ea for algebraic a ≠ 0

Notes 

Basic English 850 words
November (Nov.) is the eleventh month of the year in the Gregorian calendar, coming between October and December. It has 30 days. Its name is from the Latin word novem, which means "nine". It was the ninth month of the year before January and February were added to the Roman Calendar.

November always begins on the same day of the week as March, and additionally, February in common years.  November always ends on the same day of the week as August.

The Month 

November is the eleventh month of the year in the Gregorian calendar, after October and before December, which is the last month. November has 30 days. It was the ninth month in the old Roman calendar, which is where its name comes from. It kept its name when January and February were added to the beginning of the year, despite becoming the eleventh month. The ninth month is now September.
November begins on the same day of the week as February in common years and March every year, as each other's first days are exactly 39 weeks (273 days) and 35 weeks (245 days) apart respectively. November ends on the same day of the week as August every year, as each other's last days are exactly 13 weeks (91 days) apart.

In common years, November starts on the same day of the week as June of the previous year, and in leap years, September and December of the previous year. In common years, November finishes on the same day of the week as March and June of the previous year, and in leap years, September of the previous year.
In years immediately before common years, November starts on the same day of the week as August of the following year, and in years immediately before leap years, May of the following year. In years immediately before common years, November finishes on the same day of the week as May of the following year, and in years immediately before leap years, February and October of the following year.

In the Northern Hemisphere, November is an Autumn (Fall) month, and the further north in the hemisphere, the more likely it is to get colder as December approaches. In the Southern Hemisphere it is a Spring month. In each hemisphere, it is the seasonal equivalent of May in the other.

Several observances around the beginning of the month are believed to be related, linked to the old Celtic celebration of Samhain on November 1. These events include Halloween (October 31), Day of the Dead in Mexico (October 31 to November 2), All Saints Day (November 1) and All Souls Day (November 2).
In several mainly Christian countries, it is month in which people who died in war are commonly remembered, mainly related to the end of World War I on November 11, 1918. Near the end of the month Advent, the period leading up to Christmas, begins.

A national anthem is a country's official national song that the people of a country use to remember and respect their country. By the 18th century most countries had a national anthem and new countries chose a national anthem when they became independent. Some monarchies have a royal anthem for their monarch.

A name is a word (or a set of words) given to things and people. 

For example, cat is the name of a kind of animal. "Ryan" is a name of a person, usually a male.  "Julia" is a common female name. 

The word 'name' can also be used as a verb. To name something is to give it a name.

People's names 
In many cultures, there are rules and customs about how to give a person a name. 

Some of the rules are defined by laws, and others are defined by traditions (doing things in the way they have been done for a long time). 

There are rules about different aspects of the names and naming, including the following:

1. Number of parts of a name

In some cultures, a person has a one-part name, such as "ShiningWater." 

In other cultures, a person has a two-part name, such as "John Smith."

In some cultures, a person can have any number of name parts. In the United States, for example, some people have three: first name, middle name, and last name. Other people have only two: a first and last name.
In Chinese cultures, it is typical for a person to have three-part name, such as "Cheah Ching San," where "Cheah" is the surname. Written in English format a comma is introduced making it "Ching San, Cheah."

In Muslim and Arabic culture, a name can have one to six parts. Such as "Abdullah ibn Muhammad Al ash-Sheikh".

2. Relations with names of parents and other relatives

In some cultures, people have the same "family name" (or surname) as their parents. For example, the father of John Smith may be Mike Smith. And Mike Smith's father may be James Smith. The "Smith" part is the same for all the family. 

In other cultures, a person has the same name as his or her father, but the name is in a different place. For example, Shafiq Hanif's son may be Hanif Kamal. Hanif is in both the father's and son's name. 

3. Name changes
3. Name changes

In some cultures, a name changes when people marry, divorce, go through some religious ceremony, etc. For example, in some Spanish-speaking countries, people use two last names: their mother's father's name and their father's name. If Elena Rodriguez Gomez and Jose Sanchez Soria marry, she may change her name to Elena Rodriguez de Sanchez, and their child could be named Pilar Sanchez Rodriguez, taking the names of both of her grandfathers. 

4. Name origins

In some cultures, personal names come from history. In most European countries, some first names are taken from the Bible. In some cultures, names are taken from a relative. In other cultures, a name shows what the parents hope their child will be like. A baby may be given a name Wisdom because parents hope the baby will be a wise girl or boy.
Some cultures avoid giving people a name of an animal. For example, there is no name like dog, cat, snake, owl, or fish in Japanese people's first names. But in some cultures animal names may be good. 

5. Lengths, pronunciations, spelling, etc.

In some languages and cultures, you can tell if a word is a person's name or not by just looking at the spelling or listening to its pronunciation. There are some other linguistic patterns. For example, many Chinese names are made up of three syllables. 

6. Use of names, titles, nicknames, etc.

In some cultures, people use names when they call each other. In other cultures, people use their nicknames. In some other cultures, people use their titles ("father," "professor," etc.) when they call each other.

7. Spelling of names, titles, nicknames, etc.

8. Name awareness
8. Name awareness

Taking note of names is taken a step farther by those who elect to celebrate a name (e.g., "Celebrate Your Name Week") whether their own name, someone else's name, or names in general, complete ownership of one's name might very well include celebrating it. 9. Middle names

While some people might choose to "hide" a middle name for any number of reasons (i.e., they consider the middle name they were given to be an "embarrassment"), others have taken to celebrating their middle name (e.g., "Middle Name Pride Day").

In the English language, names exclusively are usually pronounced in correlation with the spelling, however can be pronounced as desired, e.g. John is (jon) but can also be (ned). However, not probable, is held true in the English rules of grammar.

Examples of names

Sarah, Lucy, Ellen, Claire, Ben.

Names can be shortened e.g. Isabelle can become Izzy or Belle.
Japanese names
Here are some things that are often found in Japanese names today. In the past, people went by different rules.  

1. Number of parts of a name

Japanese names have two parts. One is the family name and the other is the given name. 

"Suzuki Ichiro" is a name of a Japanese person. Suzuki is the family name, and Ichiro is the first name. In the Japanese language, the family name comes first, and the given name comes second. (It is like writing Smith John, instead of John Smith.)

Only some members of the royal family do not have a family name. 

2. Relations with names of parents and other relatives

A newborn baby gets a family name from their parents. The parents have the same family name. So, a son of Ono Yoko (female) and Ono Ken (male) is Ono something. 

The family name Ono is mostly shared by the paternal (male) part of the family. So Ono Ken's parents have the family name Ono, but Ono Yoko's parents probably do not. 

3. Name changes
3. Name changes

Names of people change when they marry and divorce. It is a custom in many parts of the world that women change their family name to that of their new husband when they marry. However, in Europe and North America especially, many women no longer do this even though their mothers and grandmothers may have. Sometimes, the man will take the woman's family name. 

4. Name origins

5. Lengths, pronunciations, spelling, etc. 

6. Use of names, titles, nicknames, etc.

Niihau (or Niʻihau) is the smallest of the inhabited islands of Hawaii, in the United States. It has a land area of 70 sq. miles (184 km2). It is the oldest of the eight main islands.

Ownership
The whole island is owned by the Robinson family. They bought it from the Kingdom of Hawaii for $10,000. It was said that the buyer, Elizabeth Sinclair (later Sinclair-Robinson), liked the island better than other places such as Waikiki, Pearl Harbor, and the island of Lanai. There is a small US Navy base where a few Navy people work.
Inhabitants
The island has a few hundred permanent inhabitants. Almost all of them are native Hawaiians. They support themselves largely with small family farms. Many work for the ranch owned by the Robinsons. The native Hawaiians lead a rural, low-tech life. They speak the Hawaiian language and keep traditions alive. This is because Ms. Sinclair promised to help preserve Hawaiian culture and tradition when she bought the island. Niihau is the only one of the Hawaiian islands where the Hawaiian language is the main language.

Tourism
Niihau is also known as the "Forbidden Island". This is due to the fact that until recently, the island was off-limits to all but family members, US Navy personnel, government officials and expressly invited guests. Now, tourists can go on one of a limited number of supervised tours or hunting safaris.
Beaches
On the beaches of the island are found shells which are the only shells to be classified as gems. Niihau shells and the jewelry made from them are very popular. Many, especially those with darker and richer color, are collectors items. The sale of shells and shell jewelry brings extra money for the local people.

Islands of Hawaii
The Nēnē, or Hawaiian goose (Branta sandvicensis) is a species of goose. It is found today on only three Hawaiian islands. It gets its name from its soft call.

This is an unmistakable species, with its generally brown plumage (feathers) and darker head. Its strong toes have much reduced webbing (skin between the toes), an adjustment to the lava flows on which it breeds. The Nēnē goes about on land much more than other water birds. When moulting (dropping old feathers and growing new ones), the Nēnē cannot fly, as do other geese, a factor which made it vulnerable to hunting.

The Nēnē was once among the most threatened waterfowl species around the world. Once common, hunting and predators brought to the islands such as mongooses, pigs and cats reduced the population to only 30 birds in the 1950s. However, this species breeds well in captivity (zoos and bird parks), and has been successfully re-introduced. There are also good numbers in wild bird collections.

The Nēnē is the state bird of Hawaii.

Internet slang is slang words which are used on the internet. Most of these words are new, such as Wiki and blog, which were not used before the internet became popular.

Some old words were given new meanings, such as mail (which now means email).  This makes many metaphors on the Internet, such as boot (which otherwise mean a shoe) and link (which otherwise means a joint in a metal chain).  Some existing acronyms, such as "AFK" (To mean "Away from keyboard") and "IRL" (To mean "In real life") were used on bulletin board systems before the internet became popular.  These are now used on the internet, such as in chat rooms and on instant messenger software.

People have also created some verbs and adjectives to describe things that only happen on the internet:

 To flame - to send offensive messages, usually in chat rooms, forums, instant messaging software or email.
 To ping - to send some data to another computer and see how long it takes for the data to come back.
Shorthand words 
Shorthand is where a word is written in a shorter way because it is quicker and easier to type. It is also done to fit more text into a limited space.

Internet slang uses many acronyms because they are quicker and easier to type.  They are often shorthand for common phrases and idioms, but they can show somebody's emotions and their certainty.

Leet speak 
Leet speak (written as: L33T or 1337) is the most common language on MMORPGs because rude words are not stopped by filters. This language is changing all the time because new words are made and used. A lot of the words use numbers instead of letters but some were made because of typing errors which are now done on purpose. Also, some suffixes are used, such as -age and -ness.

Some of the numbers and symbols used instead of letters are in the table below.
Nauru, ( ) is a island nation in the South Pacific. Its nearest neighbour is Kiribati,  east. Nauru is the smallest island nation, covering just , the smallest republic, and the only republican state without a capital. With 10,670 residents, it is the third least-populated country after Vatican City and Tuvalu.

Nauru is a phosphate rock island, and its main export since 1907 has been phosphate. English and Nauruan are the official languages. The president is Lionel Aingimea.

Geography 

Nauru is a  oval-shaped island in the southwestern Pacific Ocean,  south of the equator. The island is surrounded by a coral reef, which can be seen during low tide. Because of this, a harbor can not be built. Canals let small boats get to the island. A fertile strip  wide lies inland from the beach.
Coral cliffs surround Nauru's plateau. The highest point, the Command Ridge, is  above sea level. The only fertile areas are on the coastal belt, where coconut palms flourish. The land surrounding Buada Lagoon supports bananas, pineapples, vegetables, pandanus trees, and hardwoods such as the tomano tree.

Nauru was one of three great phosphate rock islands in the Pacific Ocean (the others were Banaba (Ocean Island) in Kiribati and Makatea in French Polynesia). The phosphate reserves on Nauru are now almost used up. Phosphate mining in the plateau has left a barren terrain of limestone pinnacles up to  high. Mining has stripped and devastated about 80 per cent of Nauru's land, and has affected the surrounding Exclusive Economic Zone. About 40 per cent of marine life has been killed by silt and phosphate runoff.
There are only about 60 native vascular plant species on the island. Coconut farming, mining, and introduced species have damaged the island's native vegetation. There are no native land mammals, but there are native insects, land crabs, and birds, including the  Nauru Reed Warbler. The Polynesian rat, cats, dogs, pigs, and chickens have been introduced to Nauru from ships.

There are only a few fresh water sources on Nauru. Storage tanks collect rainwater, but the islanders usually have to rely on desalination plants at Nauru's Utilities Agency. 

The island's biggest problems are climate change and rising sea levels. Nauru is the seventh most global warming threatened nation due to flooding. At least 80 per cent of the land of Nauru is well elevated, but this area will be uninhabitable until the phosphate mining rehabilitation programme is implemented
Climate 
Nauru's climate is hot and very humid year-round because of how close it is to the equator and the ocean. Nauru is hit by monsoon rains between November and February, but does not usually have cyclones. How much rain there is every year is highly variable, and is influenced by the El Niño-Southern Oscillation. There have been many droughts in Nauru because of this. The temperature on Nauru ranges between  and  during the day, and between  and  at night.

Administrative divisions 

Nauru is divided into fourteen administrative districts.

A noun is a kind of word (see part of speech) that is usually the name of something such as a person, place, thing, animal, or idea. In English, nouns can be singular or plural.

Nouns often need a word called an article or determiner (like the or that). These words usually do not go with other kinds of words like verbs or adverbs. (For example, people do not also describe nouns). In English, there are more nouns than any other kind of word.

Every language in the world has nouns, but they are not always used in the same ways. They also can have different properties in different languages. In some other languages, nouns do not change for singular and plural, and sometimes there is no word for the.

Examples of nouns: time, people, way, year, government, day, world, life, work, part, number, house, system, company, end, party, information.
History 
The word noun comes from the Latin nomen meaning "name." Words like nouns were described in early days by the Sanskrit grammarian Pāṇini and ancient Greeks like Dionysios Thrax. Also in ancient Tamil like "Peyarchol"

Uses of nouns 
In English sentences, nouns can be used as a subject, object, or complement. They often come after prepositions, as the 'object of preposition'.

Nouns can sometimes describe other nouns (such as a soccer ball). When they do this, they are called modifiers or adjuncts.

There are also verb forms that can be used in the same way as nouns (such as 'I like running.')  These are called verbals or verbal nouns, and include participles (which can also be adjectives) and infinitives.

Nouns are classified into common and proper. Pronouns have commonly been considered a different part of speech from nouns, but in the past some grammars have included them as nouns as do many modern linguists.
Proper nouns 
Proper nouns (also called proper name) are specific names. Examples of proper nouns are: London, John, God, October, Mozart, Saturday, Coke, Mr. Brown, Atlantic Ocean. Proper nouns are individual things with names, not general nouns.

Proper nouns begin with an upper case (capital) letter in English and many other languages that use the Roman alphabet.  (However, in German, all nouns begin with an upper case letter.) The word "I" is really a pronoun, although it is capitalized in English, like a proper noun.

Some common nouns (see below) can also be used as proper nouns. For example, someone might be named "Tiger Smith" -- even though he is not a tiger or a smith.
Common nouns 
Common nouns are general names. Sometimes the same word can be either a common noun or a proper noun, depending on how it is used; for example:
 there can be many gods, but there is only one God.
 there can be many internets (two or more networks connected together), but the largest internet in the world is the Internet.
 It is good for the heart to drink the juice of pineapple.

Countability 
In English and many other languages, nouns have 'number'. But some nouns are only singular (such as furniture, physics) and others are only plural (such as clothes, police). Also, some nouns are countable (for example, one piece, two pieces) but others are uncountable (for example, we do not say one furniture, two furnitures).

The plural form of most nouns is created simply by adding the letter(s) -(e)s.

 more than one snake = snakes
 more than one ski = skis
 more than one Barrymore = Barrymores
