Wind Erosion

What is the main thing that moves soil and sand in wind erosion?

• water

• animals walking

• wind

• fire

What kind of particles can strong wind easily carry and move?

• Large, heavy rocks

• Big tree trunks

• Water in a lake

• Small, light particles like soil and sand

Where does wind erosion happen the most?

• Under the ocean

• Dry areas like deserts

• Inside a deep cave

• Wet, rainy forests.

When the wind slows down and drops the sand it was carrying, what is this action called?

• Deflation

• Erosion

• Deposition

• Abrasion

When sand particles bounce along the ground as the wind blows, what is that movement called?

• Saltation

  (bouncing or leaping)

• Soil creep

  (rolling slowly)

• Suspension

  (floating in the air)

• Decomposition

  (being dropped)

Which landform is made when wind deposits a lot of sand in one place?

• River

• Mountain

• Cave

• Sand dune

What is one thing that holds surface particles of soil together so wind erosion can't happen as easily?

• Ice

• Water

• Strong sunlight

• Fire

What happens when sand and soil particles hit and rub against a rock or another surface?

• They make the surface stronger

• Deflation

• Abrasion

  (wearing down)

• They cause a dust storm

What is the three-step process of wind erosion in the correct order?

When many small particles of soil are carried high into the air by wind, what kind of event can happen?

• A flash flood

• A volcano eruption

• A dust storm

• A snow day
