This is a picture of slump. What caused this erosion?

Notice that the deposition is very close to where the erosion occurred! It just slid a little down the hill.

Gravity!

This is a picture of creep. What type of erosion is this???

Evidence is easiest to see when it affects the growth of trees.

Notice the color of the water. What does this mean?

This is looking down at a river from inside an airplane.

Why is the river the same color as the bare soil?

Can you see the deposition?

It is always on an inside curve because the water has to slow down there and it drops the sediment!

Rivers also empty into the sea.

The water slows down and the sediment drops out.This forms a delta.

Notice the Mississippi River runs through the dry land that has built up from the sediment it dropped once it reached the Gulf of Mexico.

When the water is underground, weathering and erosion forms caves.

As the water evaporates, the minerals that were dissolved get left behind to form the beautiful cave structures.

Notice the water dripping from the ends of the stalactites.

Stalagmites form on the floor of a cave in the place where the water is dripping from above.

As glaciers melt, they leave behind all the rocks and sediment they broken off the area through which they flowed.

Notice all the rock material that is being left behind as these glacier melts back. This is called till.

Our Appalachian Mountains looked like this millions of years ago.

Due to weathering, erosion, and deposition, they now look like this!
