Weathering, Erosion & Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is deposition?

Back

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

Front

What are the two main types of weathering?

Back

Physical weathering and chemical weathering.

Front

What is physical weathering?

Back

The breaking down of rocks without changing their chemical composition, often due to temperature changes or freeze-thaw cycles.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and substances in the environment.

Front

What role does water play in erosion?

Back

Water can carry sediments away from one place and deposit them in another, shaping landscapes over time.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one location to another.

Front

What is sediment?

Back

Small pieces of rock, minerals, and organic material that are transported by wind, water, or ice.

Front

How do plants contribute to weathering?

Back

Plant roots can grow into cracks in rocks, causing them to break apart as the roots expand.
