Earth's Layers

Erosion, volcanoes and much more!

What do you get if you mix erosion, volcanoes, a hot and dry climate and the Colorado River? If you’re really lucky and have a lot of time – at least a million years – you get the Grand Canyon. 
Located in Arizona, this huge hole in the ground shows the Earth – right down to the bone.
Erosion takes a long time to turn a desert floor into a Grand Canyon. Some scientists believe it took as long as six million years. Others believe it was much faster, taking only one million years. Either way, it was a long time!

Water erosion
Rivers and streams are moving bodies of draining water, that have a tremendous amount of force. Because of their strength, streams and rivers can cause a great amount of erosion.


Deposition

Dunes are made of sediment carried and deposited by wind. They keep their characteristic shapes even as they move. The Kelso Dunes are in the Mojave Desert.
