Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process of moving sediment from one place to another.

Front

What is chemical weathering?

Back

Chemical weathering is the breaking down of Earth’s materials by chemical processes.

Front

What happens during weathering?

Back

Weathering occurs when rocks break apart, wear away, or dissolve into smaller particles.

Front

What is a landslide?

Back

A landslide is when a lot of loose dirt and rocks move rapidly down a slope.

Front

What is the role of water in weathering?

Back

Water can wear away rocks and break them down into smaller pieces.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.

Front

What is deposition?

Back

Deposition is the process where sediment is laid down in a new location after being transported.

Front

What causes erosion?

Back

Erosion can be caused by water, wind, ice, and gravity.

Front

What is root wedging?

Back

Root wedging is a type of mechanical weathering where plant roots grow into cracks in rocks and break them apart.

Front

How do plants contribute to weathering?

Back

Plants contribute to weathering by breaking down rocks through root wedging and by producing acids that chemically weather rocks.
