Weathering, Erosion, and Deposition Flashcard

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where materials are dropped off in a new location after being transported by erosion.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks without changing their chemical composition, such as freezing and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.

Front

How does water contribute to weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart.

Front

What is the difference between weathering and erosion?

Back

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

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops off sediment, creating a delta.

Front

Is weathering and erosion the same thing?

Back

No, weathering and erosion are not the same; weathering is the breakdown of rocks, while erosion is the movement of those materials.

Front

What role do plants play in weathering?

Back

Plants can contribute to weathering through root growth that breaks apart rocks and through the production of organic acids.
