There are two theories, but the most logical one is the crash theory.
Trillions of years ago when the Earth was still a chunk of molten rock, a huge asteroid collided into the surface, taking a huge piece of our planet flying into space. The Earth's gravity pulled the material into orbit around it, and due to the universes gravity, the chunk molded into a sphere-like shape, and has been the moon ever since.
The least logical theory is the asteroid theory.
An asteroid nearly collided into Earth, and the gravitational pull from Earth and was orbiting our planet since.
Atmospheric circulation patterns keep the temperature of an area constant.
so i believe that's right...
For the answer, the question above, the similarities of both mountains and plains is that it can support any life forms like trees and animals Both types of land have a source of water which is essential for living things. For water comes from mountains and pours down to the plains.
For mountain is once a plain.
<span>Streams and creeks are examples of "watersheds." Aquifers and ground water are related to each other because both of them are located under the earths surface. You have to dig in order to acquire these two. Watersheds are just like catch-basins where waters are stored or being flowed.</span>
