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

In what way are volcanoes a constructive force?

Back

Volcanoes create new landforms and contribute to forming new soil from hardened lava.

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

Front

What is weathering?

Back

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

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of materials, while weathering is the breaking down of materials without movement.

Front

What role does gravity play in erosion?

Back

Gravity pulls materials down slopes, contributing to erosion and the movement of soil and rocks.

Front

What is sediment?

Back

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

Front

How do rivers contribute to erosion?

Back

Rivers can erode their banks and beds, carrying away sediments and shaping the landscape.
