Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the process by which rock materials are broken down by the action of physical and chemical processes.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical (mechanical) weathering and chemical weathering.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface and transported to another location.

Front

How does water contribute to erosion?

Back

Water contributes to erosion by transporting sediment and shaping landscapes.

Front

What is deposition in the context of geology?

Back

Deposition is the geological process where material is added to a landform or land mass, often after being transported by erosion.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the breaking apart of rocks due to tree roots growing into cracks.

Front

What is chemical weathering?

Back

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

Front

What role do plants play in weathering?

Back

Plants can contribute to weathering through physical means (roots breaking rocks) and chemical means (roots releasing acids that dissolve minerals).

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one location to another.

Front

What is an example of erosion caused by wind?

Back

An example of erosion caused by wind is the formation of sand dunes in desert environments.
