How Wind Changes Earth's Surface TCI Unit 3 Lesson 3

Wind causes the most weathering in

• dry areas with few plants.

• wet areas with few plants.

• dry areas with many plants.

• wet areas with many plants.

Which statement about sand dunes is NOT true?

• they are constantly changing

• they can be up to 400 m high

• they can move up to 25 m a year

• they are made from the lightest pieces of sand

Which of the following is evidence that weathering and erosion have happened?

• sand

• dust

• natural arches

• all of the answers

How does wind cause weathering?

• it picks up sand and materials

• it scrapes sand against rocks

• it slowly moves sand dunes

• it deposits sand in new places

How does wind create and destroy arches?

• through erosion alone

• through weathering alone

• through deposition alone

• through both erosion and weathering

How can wind erosion damage plants?

• flying sand cut their stems.

• covers leaves in a layer of dust

• blows away top layer of soil

• all of the answers

Because the wind picks up small pieces of sand, wind erosion causes

• less weathering.

• more weathering.

• less deposition.

• no changes.

(a)   is created by the process of deposition.​

• A sand dune

• An arch

• A dust storm

• A windbreak

A windbreak is used to

• slow down or stop the wind.

• change the direction of the wind.

• prevent dust storms from forming.

• carry small materials by the wind

A dust storm is created when a strong wind pushes a lot of

• larger pieces of sand high in the air.

• very tiny pieces of rock high in the air.

• larger pieces of sand across the ground.

• very tiny pieces of rock across the ground.
