What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals, while erosion is the movement of those materials from one place to another.

Front

What is a rapid earth change?

A rapid earth change is a quick event that alters the Earth's surface, such as a volcanic eruption or earthquake.

Front

What is a slow earth change?

Back

A slow earth change occurs gradually over time, like the wearing away of rocks by weathering.

What role do rivers play in erosion?

Back

Rivers can erode the land by carrying away soil and rocks as they flow.
