What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or other natural agents and transported to another location.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, often involving water and substances in the environment, leading to changes in the minerals.

Front

What is an example of chemical weathering?

Back

Rust on a car is an example of chemical weathering.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

What is deposition?

Back

Deposition is the process in which sediment is dropped off in a new location after being transported by wind, water, or ice.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals at the Earth's surface through physical, chemical, or biological means.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is an example of physical weathering?

Back

Ice wedging, where water freezes in cracks of rocks and expands, is an example of physical weathering.

Front

What role does water play in erosion?

Back

Water can carry away soil and rock particles, leading to erosion, especially during heavy rains or floods.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock from one location to another, while weathering is the process of breaking down rocks without movement.
