3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move.
4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea.
5. An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption.
6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter.

13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
14.
Answer:
D. The concentration of salt becomes so high that all plant life is destroyed.
Explanation:
As time passes, the structure of an ecological community gradually changes leading to formation of new species. This is known as <u>ecological succession</u>.
The various processes above show an example of how ecological succession occurs over time. <u>However, it doesn't indicate at any point that plant life is destroyed due to high concentration of salt.</u>
The salt marsh that results actually supports plant life in the form of mangrove trees.
Answer: Option C) Pluto
Explanation:
