Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process of wearing away rocks, soil, and other materials on the Earth's surface through the action of water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process of adding sediments, soil, and rocks to a landform or landmass.

How is a delta formed?

Back

A delta is formed by sediments when a river deposits sediment at its mouth where it meets a body of water.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away particles and shaping the landscape.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials from one location to another.

Front

What is a beach?

Back

A beach is formed through the accumulation of sand, gravel, and other sediment deposited along the shoreline by natural processes such as wave action and currents.

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 chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their dissolution or formation of new minerals.

Front

What is biological weathering?

Back

Biological weathering occurs when living organisms, such as plants and animals, contribute to the breakdown of rocks.
