Answer the following question given this paragraph: Geology is the study of the solid Earth. Geologists study how rocks and minerals form. The way mountains rise up is part of geology. The way mountains erode away is another part. Geologists also study fossils and Earth's history. There are many other branches of geology. There is so much to know about our home planet that most geologists become specialists in one area. For example, a mineralogist studies minerals, as seen in ( Figure below ). Q: What is the name of the scientific field that deals with the general study of the solid earth? A:
****
A: geology

Answer the following question given this paragraph: In displacement versus time graphs, the slope of the line is the velocity of the object. In this case of a velocity versus time graph, the slope of the line is the acceleration. If you take any segment of this line and determine the to ratio, you will get 6.0 m/s 2 which we know to be the constant acceleration of this object. Q: When two of these meet, the result is often a storm? A:
OPTIONS:
- air pockets
- electromagnetic waves
- tectonic plates
- air masses
air masses

Answer the following question given this paragraph: Distance is the length of the route between two points. The distance of a race, for example, is the length of the track between the starting and finishing lines. In a 100-meter sprint, that distance is 100 meters. Q: What is the length of the route between two points? A:
OPTIONS:
- speed
- direction
- velocity
- distance

Answer: distance

Question: Answer the following question given this paragraph: Water is the main ingredient of many solutions. A solution is a mixture of two or more substances that has the same composition throughout. Some solutions are acids and some are bases. To understand acids and bases, you need to know more about pure water. In pure water (such as distilled water), a tiny fraction of water molecules naturally breaks down to form ions. An ion is an electrically charged atom or molecule. The breakdown of water is represented by the chemical equation. Q: What is the term for a mixture of two or more substances that has the same composition throughout? A:
OPTIONS:
- fluid
- simple liquid
- structure
- solution
Answer: solution

input: OPTIONS:
- neutral compounds
- zero charged compunds
- zeronic ions
- ionic compounds Now, answer this question: Answer the following question given this paragraph: Summary The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces. Mostcovalent compounds consist of molecules, groups of atoms in which one or more pairs of electrons are shared by at least two atoms to form a covalent bond. The atoms in molecules are held together by the electrostatic attractionbetween the positively charged nuclei of the bonded atoms and the negatively charged electrons shared by the nuclei. The molecular formula of a covalent compound gives the types and numbers of atoms present. Compounds that contain predominantly carbon and hydrogen are called organic compounds, whereas compounds that consist primarily of elements other than carbon and hydrogen areinorganic compounds. Diatomic molecules contain two atoms, andpolyatomic molecules contain more than two. A structural formula indicates the composition and approximate structure and shape of a molecule. Single bonds, double bonds, and triple bonds are covalent bonds in which one, two, and three pairs of electrons, respectively, are shared between two Saylor URL: http://www. saylor. org/books.
