Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process of moving sediment from one place to another by natural forces such as water, wind, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes.

Front

What is deposition?

Back

Deposition is the process where sediment is dropped off in a new location after being transported by erosion.

Front

How do weathering, erosion, and deposition affect Earth's features?

Back

They shape and change the landscape, creating valleys, mountains, and other geographic features.

Front

What is a landslide?

Back

A landslide is a sudden and rapid movement of rocks and soil down a slope.

Front

What can cause landslides?

Back

Landslides can be caused by earthquakes, volcanic eruptions, or heavy rains.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to water and other chemicals.

Front

What role does water play in erosion?

Back

Water can carry away soil and sediment, leading to erosion of land and changes in landscape.

Front

What is the difference between erosion and weathering?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.
