             3. Why does the earth look the way it does?

There are many types of surfaces and grounds on planet earth. for example, there are canyons. Usually canyons are there because in the beginning it was a deep body of water, then the water vanished which caused a canyon. The second type of landform is the valley. A valley is formed by a river that erodes, this experience takes thousands of years to occur. The third type of landform is the grassy plains, this is usually a flat surface that is grassy. Usually all the farms are there. Thats some of the basic landforms in the world.
