Weathering, Erosion, and Deposition

Front

What is Weathering?

Back

The process of breaking down rocks and other materials on Earth's surface without changing their chemical composition.

Front

What is Erosion?

Back

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

Front

What is Deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass.

Front

What is Mechanical Weathering?

Back

A type of weathering that breaks down rocks into smaller pieces without changing their chemical composition.

Front

What is Chemical Weathering?

Back

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

Front

How does acid rain contribute to weathering?

Back

Acid rain can dissolve minerals in rocks, leading to chemical weathering and the formation of features like caves.

Front

What role does water play in erosion?

Back

Water can carry away soil and sediments, especially during heavy rains or floods, leading to erosion.

Front

What is an example of erosion caused by wind?

Back

Desert landscapes where wind removes loose sand and soil, shaping the terrain.

Front

How do glaciers contribute to erosion?

Back

Glaciers can carve out valleys and transport large amounts of rock and sediment as they move.

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.
