Unit 4: Changes to Earth's Surfaces

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 deposition?

Back

The process of dropping rocks, soil, or other materials from one place to a new location on the Earth's surface by natural forces.

Front

What type of processes are involved in the formation of a sand dune?

Back

Both, Destructive and Constructive processes.

Front

What is the main cause of sand dune formation?

Back

Wind erosion and deposition.

Front

What natural forces can cause erosion?

Back

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

Front

What is a constructive process that contributes to landform creation?

Back

Deposition.

Front

What is the difference between constructive and destructive processes?

Back

Constructive processes build up landforms, while destructive processes wear them down.

Front

How does water contribute to erosion?

Back

Water can flow over land, carrying away soil and rocks.

Front

What role does wind play in shaping the Earth's surface?

Back

Wind can erode materials and deposit them elsewhere, forming features like sand dunes.

Front

What is weathering?

Back

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