Weathering, erosion, deposition

Front

What is erosion?

Back

Erosion is the process when earth materials are carried away or worn away by natural forces like wind or water.

Front

Which landform is NOT created by deposition?

Back

Mountains are not created by deposition.

Front

What is a delta?

Back

A delta is a landform that is a result of the deposition of sediments at the mouth of a river.

Front

What is chemical weathering?

Back

Chemical weathering is the process where rocks break down due to chemical reactions, such as acid rain breaking down rock.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process where rocks break down physically, such as rocks falling off a cliff and breaking.

Front

What natural forces contribute to erosion?

Back

Natural forces that contribute to erosion include wind, water, and ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down or deposited in a new location.

Front

Give an example of a landform created by deposition.

Back

Examples of landforms created by deposition include deltas, beaches, and sand dunes.

Front

What is the freeze-thaw process?

Back

The freeze-thaw process is a type of mechanical weathering where water seeps into cracks in rocks, freezes, expands, and causes the rocks to break apart.

Front

How does acid rain affect rocks?

Back

Acid rain can chemically weather rocks by breaking down minerals and altering their composition.
