Weathering is the process by which rock materials are broken down by the action of physical or chemical processes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

What is deposition?

Back

Deposition occurs when eroded materials are dropped, or laid down, in a new location.

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, such as oxidation or acid rain.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks rocks into smaller pieces without changing their chemical composition, often due to temperature changes or pressure.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is a rock turning a reddish color when exposed to air and water.

Front

What is an example of physical weathering?

Back

An example of physical weathering is a rock in a windy desert having scratches on its surface.

Front

What role do plants play in weathering?

Back

Plants can produce weak acids that contribute to chemical weathering of rocks.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one place to another.

Front

What is sediment?

Back

Sediment is small pieces of rock and soil that are transported by wind, water, or ice.
