Unit 4: Changes to Earth's Surfaces

Front

What is the process by which a sand dune is formed?

Back

Wind erosion and deposition.

Front

Which type of process is involved in the formation of a sand dune?

Back

Both, Destructive and Constructive.

Front

What is deposition?

Back

The process of adding sediments, soil, or rocks to a landform or new location.

Front

In what ways can erosion occur?

Back

Water flow, wind action, ice movement, and gravity.

Front

What is erosion?

Back

The process of moving away rock, soil, or other materials on the Earth's surface by natural forces such as water, wind, or ice.

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by natural forces.

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 into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, changing their composition.

Front

What role does gravity play in erosion?

Back

Gravity pulls materials down slopes, contributing to erosion and sediment movement.
