Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces like wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where materials like sand and sediment are dropped off in a new location after being transported by erosion.

Front

How does wind contribute to erosion?

Back

Wind can blow sand and small particles from one place to another, wearing down surfaces and moving materials.

Front

What happens during freeze-thaw weathering?

Back

Water gets into cracks in rocks, freezes, expands, and causes the rocks to break apart.

Front

Can you give an example of deposition?

Back

An example of deposition is when a river slows down and drops off sand and silt, forming a delta.

Front

What role does water play in weathering?

Back

Water can cause weathering by dissolving minerals, freezing in cracks, and wearing away surfaces.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a new location.

Front

How do plants help prevent erosion?

Back

Plants help prevent erosion by holding soil in place with their roots, reducing the impact of wind and water.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.
