Weathering, Erosion, Deposition

Front

What is weathering?

Back

The process by which rocks are broken down into smaller pieces.

Front

What is erosion?

Back

The movement of weathered materials from one location to another, often by water, wind, or ice.

Front

What is deposition?

Back

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

Front

What is chemical weathering?

Back

The breakdown of rocks through chemical reactions, often involving water and gases.

Front

What is physical weathering?

Back

The mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is an example of chemical weathering?

Back

Iron in rocks reacting with oxygen to form iron oxide (rust).

Front

What is an example of physical weathering?

Back

Water gradually wearing down and smoothing rocks over a long period of time.

Front

What role does water play in erosion?

Back

Water can carry away sediments and rocks, shaping landscapes through erosion.

Front

What is mechanical weathering?

Back

A type of physical weathering that involves the physical breaking down of rocks into smaller pieces.

Front

How does temperature affect weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to cracks and breaking.
