Weathering, Erosion & Deposition

Front

What is deposition?

Back

Deposition is when particles carried by water, ice, or wind are dropped in another location.

Front

True or False: Some types of weathering are caused by water, wind, ice, temperature, and plant roots.

Front

How can deposition change the Earth’s surface over long periods of time?

Back

Deposition may change the Earth’s surface by forming new land features.

Front

What is erosion?

Back

Erosion is the movement of sediment or soil from one location to another by water, ice, or wind.

Front

What are the main causes of weathering?

Back

Weathering can be caused by water, wind, ice, temperature changes, and plant roots.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken materials.

Front

Give an example of deposition.

Back

An example of deposition is when a river drops sand and silt at its mouth, forming a delta.

Front

What role do plants play in weathering?

Back

Plants can cause weathering through their roots, which can break apart rocks.

Front

What is mechanical weathering?

Back

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