T4L4 - Weathering and Erosion

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 process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

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

Front

How does rainfall affect weathering?

Back

Rainfall can accelerate weathering by providing water that can chemically break down minerals and physically wear away rocks.

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks without changing their chemical composition, often due to temperature changes, freeze-thaw cycles, or abrasion.

Front

What is chemical weathering?

Back

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

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by carrying away loose particles, especially in dry and sandy environments.

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 to new locations.

Front

What is an example of biological weathering?

Back

Biological weathering occurs when plants, animals, or microorganisms break down rocks, such as roots growing into cracks.

Front

What is a common effect of erosion on landscapes?

Back

Erosion can lead to the formation of valleys, canyons, and other landforms by removing soil and rock.
