Weathering, Erosion, Deposition

Front

What is erosion?

Back

The process of moving pieces of rock and soil by water, ice, wind, or gravity.

Front

What are the causes of weathering?

Back

Water, wind, ice, and plant roots.

Front

How are new landforms created from deposited material?

Back

By waves depositing sediment offshore.

Front

How can water contribute to weathering?

Back

By freezing and expanding in rock cracks.

Front

What is a result of constant erosion by the Colorado River?

Back

The Grand Canyon.

Front

Define weathering.

Back

The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

What is deposition in the context of geology?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass.

Front

Explain the difference between mechanical and chemical weathering.

Back

Mechanical weathering involves the physical breakdown of rocks without changing their chemical composition, while chemical weathering involves changes in the chemical structure of minerals.

Front

What role do plant roots play in weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart.

Front

How does ice contribute to weathering?

Back

Ice can freeze in rock cracks, expand, and cause the rocks to fracture.
