This force that moves rock and other materials downhill?
What is gravity?
100
This is what happens to rock when it is weathered.

100
This often occurs when water soaks the base of a mass of soil that is rich in clay.

The wearing away of rock by a grinding action.

A meander that has been cut off from the river?
What is an oxbow lake?

This term describes the movement of soil from one place to another.
What is erosion?

A very slow downhill movement of rock and soil.
What is a creep?
400

What is deposition?
500
The lower the pH value of a substance, the more acidic that substance is. Rain in City A has a pH of 3, rain in City B has a pH of 5, and rain in City C has a pH of 4. If each city had about the same amount of rain, which city would have the most chemical erosion?
What is City A?

Often results from the freezing and thawing of water in cracked layers of rock beneath the soil.
