Why is it necessary to have a constant input of energy into an ecosystem?
IrinaK [193]
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.

3.Why is the surface of the Earth in constant motion?
tekilochka [14]
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. 

7. Depends on what kind you're looking for. I'd look it up for your specific topic.

8. To apply a forces to something, usually resulting in a stretch.

9.  The action of compressing something, to flatten or squeeze by pressure

10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.

11. In areas undergoing extension or stretching. It's when the crust is extended. 

12.  The hanging wall drops relative to the footwall. 

13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
