Weathering, Erosion and Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered materials from one location to another by natural forces such as water, wind, ice, or gravity.

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What are sediments?

Back

Sediments are small particles of rock, soil, and organic material that have been broken down by weathering and transported by erosion.

What role do roots play in preventing erosion?

Back

Roots of plants hold soil in place, helping to prevent erosion by stabilizing the ground.

Front

What are dunes?

Back

Dunes are mounds of wind-deposited sand found in deserts and along shorelines.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

How does gravity contribute to erosion?

Back

Gravity causes materials to move downhill, leading to processes like landslides and rockfalls, which contribute to erosion.

What is the difference between weathering and erosion?

Back

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