Which of the following helps protect the coastline from erosion?

• sand dunes

• mesas

• barrier islands

• plains

How can moving water cause erosion?

• As the water slows, sediment settles to the ground.

• Water quickly cools magma that reaches the Earth's surface.

• As moving water seeps into faults, mud and soil fill the cracks.

• As the water flows, it wears away rocks and carries sediment along with it.

A. occurs when gravity makes the soil, mud, and rocks move suddenly down a slope.
