Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process by which rocks and minerals are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces like water, wind, or ice.

Front

What process smooths rocks in a river?

Back

Weathering occurs when rocks are worn down by the action of water.

Front

What is the main difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to a different location.

Front

What natural force can cause erosion?

Back

Water, wind, and ice are natural forces that can cause erosion.

Front

What is an example of deposition?

Back

An example of deposition is the formation of a delta at the mouth of a river.

Front

What happens to rocks during weathering?

Back

Rocks are broken down into smaller pieces.
