Weathering, Erosion, Deposition

Front

What is mechanical weathering?

Back

Mechanical weathering is the process in which rocks are physically broken into smaller pieces without changing their chemical composition.

Front

What type of sediment does wind erosion most strongly affect?

Back

Wind erosion most strongly affects loose, sandy soil.

Front

True or False: Rain does not move sediment.

Back

False. Rain can move sediment.

Front

What is deposition?

Back

Deposition is the dropping off or depositing of rocks and sediment in a new location.

Front

Which agent is most likely responsible for the formation of sand dunes?

Back

Wind is the agent most likely responsible for the formation of sand dunes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind, water, and ice.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, changing their mineral composition.

Front

What role does gravity play in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion by pulling rocks and soil down slopes.

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 from one place to another.

Front

What is an example of a natural agent of erosion?

Back

Water is a natural agent of erosion, as it can carry sediment away from its source.
