Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one place to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass.

Front

What causes physical weathering?

Back

Physical weathering is caused by natural forces such as temperature changes, freezing and thawing, and the growth of plant roots.

Front

What is chemical weathering?

Back

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

Front

How do tree roots contribute to weathering?

Back

Tree roots can grow into cracks in rocks, expanding them and causing physical weathering.

Front

What role does freezing water play in weathering?

Back

Freezing water expands in cracks of rocks, causing them to break apart, which is a form of physical weathering.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the breaking of rocks due to extreme temperature changes.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is the rusting of iron in rocks when it reacts with oxygen and water.

Front

How does wind contribute to erosion?

Back

Wind can carry away loose particles of soil and sand, leading to erosion in dry areas.
