Answer:
Slow cooling leads to the formation of large crystals. If the crystals remain undisturbed while cooling, they grow according to a regular pattern. Magma closer to the surface cools much faster than magma that hardens deep below ground. With rapid cooling, there is no time for magma to form large crystals.

Answer:
Hydrogen bonding
Explanation:
Water is a compound found readily in nature. It is made up of interatomic forces of covalent bonds that connects the hydrogen and oxygen bonds together in a definite ratio.
- The intermolecular forces are responsible for the physical properties of substances.
- These forces allows a compound to behave in certain ways.
- In water, the intermolecular bonding present are the very strong hydrogen bonds.
- For this bond type, the hydrogen of one water molecule is firmly attached to the oxygen of another water molecule.
- The bonds are very strong forces.
Answer:
Answer C: It can affect fish and other marine life.
Explanation:
Hydropower plants can harm ecosystems, especially killing fish with their turbines.
Note: Hydropower generators do not directly emit air pollutants. However, dams, reservoirs, and the operation of hydroelectric generators can affect the environment. And greenhouse gases (GHG) such as Carbon Dioxide (MENTIONED IN ANSWER A) and methane form in natural aquatic systems and in human-made water storage reservoirs as a result of the aerobic and anaerobic decomposition of biomass in the water.
However, if we can choose just the only one answer, then the answer is C.
