Weathering, Erosion, and Deposition

Front

What is mechanical weathering?

Back

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

Front

What is chemical weathering?

Back

Chemical weathering is the process that involves the chemical alteration of minerals in rocks, leading to the formation of new minerals and soluble substances.

Front

What is erosion?

Back

Erosion is the process of moving sediment and soil from one location to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediment is dropped or left in a new location after being transported by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks into smaller pieces, while erosion is the movement of those pieces from one place to another.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering and chemical weathering.

Front

What role does water play in weathering?

Back

Water can cause both mechanical weathering (through freeze-thaw cycles) and chemical weathering (by dissolving minerals).

Front

How does temperature affect weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to mechanical weathering.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is the breaking of rocks by ice wedging, where water freezes in cracks and expands.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is the reaction of carbon dioxide with water to form carbonic acid, which can dissolve limestone.
