Weathering, Erosion & Deposition

Front

What is weathering?

Back

The process by which rock materials are broken down by the action of physical and chemical processes.

Front

What is erosion?

Back

The process by which weathered materials are transported from one location to another by wind, water, ice, or gravity.

Front

What is deposition?

Back

When eroded materials are dropped or laid down in a new location.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, such as oxidation and acid precipitation.

Front

What is physical weathering?

Back

The process that breaks down rocks into smaller pieces without changing their chemical composition, often through temperature changes or freeze-thaw cycles.

Front

What is oxidation in weathering?

Back

A type of chemical weathering where oxygen reacts with minerals in rocks, often leading to rusting.

Front

What role does water play in erosion?

Back

Water can carry sediment and rocks away from their original location, shaping landscapes through erosion.

Front

What happens to sediment when a river slows down?

Back

The river loses energy and drops sediment, leading to deposition.

Front

What is the difference between weathering and erosion?

Back

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

Front

What is sediment?

Back

Small particles of rock and soil that are transported by wind, water, or ice.
