Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and other materials on Earth's surface without moving them.

Front

What is erosion?

Back

Erosion is the process where rocks and soil are moved from one location to another by wind, water, or ice.

Front

What is deposition?

Back

Deposition occurs when eroded materials stop moving and begin to build up in a new location.

Front

How does weathering affect rocks?

Back

Weathering breaks down large rocks into smaller pieces, changing their size and shape.

Front

What can deposition create over time?

Back

Deposition can form new land features such as deltas, beaches, and sand dunes.

Front

Give an example of erosion.

Back

A farmer's topsoil being blown away during a hurricane is an example of erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down materials without moving them, while erosion involves the movement of those materials.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles and chemical reactions.

Front

What is mechanical weathering?

Back

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

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their breakdown.
