A mudflow is a rapid flow of water-saturated soil and debris down a slope, often occurring after heavy rainfall.

Front

What is the difference between erosion and weathering?

Back

Weathering breaks down rocks into smaller pieces, while erosion involves the movement of those pieces from one location to another.

Front

What are the main causes of erosion?

Back

The main causes of erosion include water, wind, ice, and gravity.
