Weathering, Erosion, & Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces like water, wind, or ice.

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.

How does freeze-thaw weathering work?

Back

Freeze-thaw weathering occurs when water enters cracks in rocks, freezes, expands, and causes the rock to break apart.

What role do glaciers play in deposition?

Back

Glaciers carry rocks and sediments as they move, and when they melt, they drop these materials, leading to deposition.

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 a different location.

Front

What is chemical weathering?

Back

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

What is physical weathering?

Back

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