Weathering

Front

What is weathering?

Back

Weathering is the natural chemical or physical processes that break down rock on Earth's surface.

Front

What is chemical weathering?

Back

Chemical weathering occurs when rocks weaken and break down due to chemical changes in the composition of the rock.

Front

What is mechanical weathering?

Back

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

Front

What is erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves weathered rock and soil from one place to another.

Front

How does weathering affect mountains?

Back

Weathered mountains appear rounder and less jagged compared to unweathered mountains.

Front

What causes rusting in rocks?

Back

Exposure to rain and oxygen causes the metal minerals in rocks to rust, which is an example of chemical weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What role does water play in weathering?

Back

Water can cause both chemical weathering (by reacting with minerals) and physical weathering (by freezing and thawing).

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur without erosion; rocks can break down in place without being moved.
