Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the breaking down of rocks.

Front

What happens during weathering?

Back

Rocks on Earth's surface break apart or change without moving anywhere.

Front

What caused the Grand Canyon?

Back

The Grand Canyon was caused by water erosion from the Colorado River.

Front

What is erosion?

Back

Erosion is the process that moves rocks from one place to another.

Front

What is an example of weathering?

Back

Flood water pounding against a canyon wall and wearing it down.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations.

Front

What are the main agents of erosion?

Back

Water, wind, ice, and gravity are the main agents of erosion.

Front

How does wind cause erosion?

Back

Wind can carry small particles away from one place and deposit them in another.

Front

What is ice wedging?

Back

Ice wedging is a type of weathering where water freezes in cracks of rocks, causing them to break apart.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and soil down slopes, contributing to erosion.
