Question: The northern part of this park contains the Hetch Hetchy Valley, which was controversially dammed against the advice of John Muir. Ansel Adams took black-and-white photographs of this park, including one of the moon over the granite formation called Half Dome. A waterfall that feeds the Merced River shares its name with, for 10 points, what national park in the Sierra Nevada of California?
Answer: Yosemite National Park

Yosemite National Park ( yoh-SEM-ih-tee) is a national park in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 759,620 acres (1,187 sq mi; 3,074 km2) in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada.
Its geology is characterized by granite and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and tilted to form its unique slopes, which increased the steepness of stream and river beds, forming deep, narrow canyons. About one million years ago glaciers formed at higher elevations. They moved downslope, cutting and sculpting the U-shaped Yosemite Valley.
European American settlers first entered the valley in 1851. Other travelers entered earlier, but James D. Savage is credited with discovering the area that became Yosemite National Park. Native Americans had inhabited the region for nearly 4,000 years, although humans may have first visited as long as 8,000 to 10,000 years ago.
Yosemite was critical to the development of the concept of national parks. Galen Clark and others lobbied to protect Yosemite Valley from development, ultimately leading to President Abraham Lincoln's signing of the Yosemite Grant of 1864 that declared Yosemite as federally preserved land. In 1890, John Muir led a successful movement to motivate Congress to establish Yosemite Valley and its surrounding areas as a National Park. This helped pave the way for the National Park System. Yosemite draws about four million visitors annually. Most visitors spend the majority of their time in the valley's seven square miles (18 km2). The park set a visitation record in 2016, surpassing five million visitors for the first time. in 2023, the park saw nearly 4 million visitors.

Question: This constellation's alpha star is the brightest in the Hyades ("HIGH"-uh-deez) cluster. One object in this constellation is the remnant of a supernova observed in 1054 AD. In addition to the Crab Nebula, this constellation also contains the Pleiades (PLEE-uh-deez). Its beta star, Al Nath, is found next to Auriga, while its alpha star is Aldebaran (all-DEB-uh-ron). For 10 points, name this constellation that depicts a bull.
Answer: {Taurus}

Taurus (Latin, 'Bull') is one of the constellations of the zodiac and is located in the northern celestial hemisphere. Taurus is a large and prominent constellation in the Northern Hemisphere's winter sky. It is one of the oldest constellations, dating back to the Early Bronze Age at least, when it marked the location of the Sun during the spring equinox. Its importance to the agricultural calendar influenced various bull figures in the mythologies of Ancient Sumer, Akkad, Assyria, Babylon, Egypt, Greece, and Rome. Its old astronomical symbol is  (♉︎), which resembles a bull's head.
A number of features exist that are of interest to astronomers. Taurus hosts two of the nearest open clusters to Earth, the Pleiades and the Hyades, both of which are visible to the naked eye. At first magnitude, the red giant Aldebaran is the brightest star in the constellation. In the northeast part of Taurus is Messier 1, more commonly known as the Crab Nebula, a supernova remnant containing a pulsar. One of the closest regions of active star formation, the Taurus-Auriga complex, crosses into the northern part of the constellation. The variable star T Tauri is the prototype of a class of pre-main-sequence stars.

Question: Calderas are formed from the collapse of these objects, which can be divided into composite, shield, and cinder cone types. The Hawaiian Islands were formed from these landforms, which are most commonly found in the Ring of Fire. For 10 points, name these landforms that can be classified as active, dormant, or extinct based on the time they last erupted.
Answer: volcanoes

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, 3,000 kilometers (1,900 mi) deep within Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide past one another.
Large eruptions can affect atmospheric temperature as ash and droplets of sulfuric acid obscure the Sun and cool Earth's troposphere. Historically, large volcanic eruptions have been followed by volcanic winters which have caused catastrophic famines.
Other planets besides Earth have volcanoes. For example, volcanoes are very numerous on Venus. In 2009, a paper was published suggesting a new definition for the word 'volcano' that includes processes such as cryovolcanism. It suggested that a volcano be defined as 'an opening on a planet or moon's surface from which magma, as defined for that body, and/or magmatic gas is erupted.'
This article mainly covers volcanoes on Earth. See § Volcanoes on other celestial bodies and Cryovolcano for more information.

Question: This mountain range includes the Vilcabamba (“VEEL-cuh-BOM-buh”) sub-range and contains a plateau called the altiplano (“ALL-tee-PLAN-oh”). It is home to the tallest volcano on Earth, Ojos (“OH- hoess”) del Salado, and the highest peak in the Western Hemisphere, Aconcagua (“AH-con-CAH-gwa”). Llamas were domesticated in, for 10 points, what longest mountain range on Earth, located in western South America?
Answer: {Andes} Mountains

The Andes ( AN-deez), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,530 mi) long and 200 to 700 km (124 to 435 mi) wide (widest between 18°S and 20°S latitude) and has an average height of about 4,000 m (13,123 ft). The Andes extend from South to North through seven South American countries.:  Argentina, Chile, Bolivia, Peru, Ecuador,  Colombia and western Venezuela.
Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano Plateau is the world's second-highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.
The Andes Mountains are the highest mountain range outside Asia. The range’s highest peak, Argentina's Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m (22,615 ft).
The Andes are also part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of the Americas and Antarctica.

Question: This river was known in ancient times as the "Black" River due to the black silt it deposited during floods. Lake Tana is one source of this river; John Speke discovered that the other was Lake Victoria. It forms from the confluence of namesake Blue and White Rivers near Khartoum. For 10 points, Aswan High Dam is on what longest river in the world?
Answer: {Nile} River

The Nile is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa and has historically been considered the longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer. Of the world's major rivers, the Nile is one of the smallest, as measured by annual flow in cubic metres of water. About 6,650 km (4,130 mi) long, its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt, Sudan and South Sudan. Additionally, the Nile is an important economic river, supporting agriculture and fishing.
The Nile has two major tributaries: the White Nile and the Blue Nile. The White Nile is traditionally considered to be the headwaters stream. However, the Blue Nile is the source of most of the water of the Nile downstream, containing 80% of the water and silt. The White Nile is longer and rises in the Great Lakes region. It begins at Lake Victoria and flows through Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at the Sudanese capital of Khartoum.
The northern section of the river flows north almost entirely through the Nubian Desert to Cairo and its large delta, and the river flows into the Mediterranean Sea at Alexandria. Egyptian civilization and Sudanese kingdoms have depended on the river and its annual flooding since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of the Aswan Dam. Nearly all the cultural and historical sites of Ancient Egypt developed and are found along river banks. The Nile is, with the Rhône and Po, one of the three Mediterranean rivers with the largest water discharge.

Question: This musician sang duets like "Let's Call the Whole Thing Off" with Ella Fitzgerald and recorded albums with his "Hot Five" and "Hot Seven" bands. He sang "It's so nice to have you back where you belong" in one song, and described "Bright blessed days" and "dark sacred nights" in another song. (*) For 10 points, what jazz trumpeter, nicknamed "Satchmo" sang "Hello, Dolly!" and "What a Wonderful World"?
Answer: Louis Armstrong

Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed "Satchmo", "Satch", and "Pops", was an American trumpeter and vocalist. He was among the most influential figures in jazz. His career spanned five decades and several eras in the history of jazz. Armstrong received numerous accolades including the Grammy Award for Best Male Vocal Performance for Hello, Dolly! in 1965, as well as a posthumous win for the Grammy Lifetime Achievement Award in 1972, and induction into the National Rhythm & Blues Hall of Fame in 2017.
Armstrong was born and raised in New Orleans. Coming to prominence in the 1920s as an inventive trumpet and cornet player, he was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. Around 1922, Armstrong followed his mentor, Joe "King" Oliver, to Chicago to play in the Creole Jazz Band. Armstrong earned a reputation at "cutting contests", and his fame reached band leader Fletcher Henderson. Armstrong moved to New York City, where he became a featured and musically influential band soloist and recording artist. By the 1950s, Armstrong was a national musical icon, appearing regularly in radio and television broadcasts and on film.
Armstrong's best known songs include "What a Wonderful World", "La Vie en Rose", "Hello, Dolly!", "On the Sunny Side of the Street", "Dream a Little Dream of Me", "When You're Smiling" and "When the Saints Go Marching In". He collaborated with Ella Fitzgerald, producing three records together: Ella and Louis (1956), Ella and Louis Again (1957), and Porgy and Bess (1959). He also appeared in films such as A Rhapsody in Black and Blue (1932), Cabin in the Sky (1943), High Society (1956), Paris Blues (1961), A Man Called Adam (1966), and Hello, Dolly! (1969).
With his instantly recognizable rich, gravelly voice, Armstrong was also an influential singer and skillful improviser. He was also skilled at scat singing. By the end of Armstrong's life, his influence had spread to popular music in general. He was one of the first popular African-American entertainers to "cross over" to wide popularity with White and international audiences. Armstrong rarely publicly discussed racial issues, to the dismay of fellow African Americans, but took a well-publicized stand for desegregation in the Little Rock crisis. He was able to access the upper echelons of American society at a time when this was difficult for Black men.

Question: The Tibesti Mountains are a prominent feature of this desert that also contains sand seas called ergs. The Tuareg people are nomadic inhabitants of this desert, which was crossed in medieval times by a caravan route to Timbuktu. The Sahel is the southern border of this desert that covers much of Mauritania, Niger, and Libya. For 10 points, name this desert that covers most of North Africa.
Answer: Sahara Desert

The Sahara (, ) is a desert spanning across North Africa. With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
The name "Sahara" is derived from Arabic: صَحَارَى, romanized: ṣaḥārā /sˤaħaːraː/, a broken plural form of ṣaḥrā' (صَحْرَاء /sˤaħraːʔ/), meaning "desert".
The desert covers much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and the Sudan.
It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan region of sub-Saharan Africa. The Sahara can be divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, and the Libyan Desert.
For several hundred thousand years, the Sahara has alternated between desert and savanna grassland in a 20,000-year cycle caused by the precession of Earth's axis (about 26,000 years) as it rotates around the Sun, which changes the location of the North African monsoon.

Question: This is the only number that satisfies the equation sine x equals x. The additive inverse property says that the sum of any number and its additive inverse equals this number, while the additive identity property says that any number plus this number equals the original number. For 10 points, name this only non-positive whole number, which yields itself when multiplied by any number.
Answer: {zero}

0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 has the result 0, and consequently, division by zero has no meaning in arithmetic.
As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, "205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya.
Common names for the number 0 in English include zero, nought, naught (), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (). Informal or slang terms for 0 include zilch and zip. Historically, ought, aught (), and cipher have also been used.

Question: This poet delivered "The Gift Outright" at President John F. Kennedy's inauguration. One of his poems observes that "good fences make good neighbors" and is called "Mending Wall." His poem "Nothing Gold Can Stay" notes that "Nature's first green is gold." For 10 points, name this poet who stated in his most famous poem that he took "the road less traveled by, and that has made all the difference."
Answer: Robert Lee Frost

Robert Lee Frost (March 26, 1874 – January 29, 1963) was an American poet. His work was initially published in England before it was published in the United States. Known for his realistic depictions of rural life and his command of American colloquial speech, Frost frequently wrote about settings from rural life in New England in the early 20th century, using them to examine complex social and philosophical themes.
Frequently honored during his lifetime, Frost is the only poet to receive four Pulitzer Prizes for Poetry. He became one of America's rare "public literary figures, almost an artistic institution". He was awarded the Congressional Gold Medal in 1960 for his poetic works. On July 22, 1961, Frost was named poet laureate of Vermont.

Question: The island of Bornholm is in this body of water, which is connected by the Kiel (“KEEL”) Canal to the North Sea. One arm of this sea is the Gulf of Bothnia, and the large island of Saaremaa (“SAH-reh- MAH”) guards its Gulf of Riga (“REE-guh”). Five national capitals lie on this body of water, including Tallinn, the capital of Estonia, and Stockholm. For 10 points, name this sea south of Scandinavia.
Answer: {Baltic} Sea

The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North and Central European Plain.
The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. It is a shelf sea and marginal sea of the Atlantic with limited water exchange between the two, making it an inland sea. The Baltic Sea drains through the Danish straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia (divided into the Bothnian Bay and the Bothnian Sea), the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk.
The "Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula.
The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German Bight of the North Sea via the Kiel Canal.
