ES Ch. 10 - Erosion & Weathering

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.

The process that breaks down rocks and other materials on Earth's surface is called

• Weathering
• Erosion

What is the process that picks up and moves weathered rocks?

• Erosion
• Landslide
• Weathering

What causes the greatest erosion effect on our beaches?

• Waves
• Gravity
• Glaciers
• Wind

The process by which water, ice, wind, or gravity moves weathered rock and soil from one place to another.

• Weathering
• Erosion
• Deposition
• Crop Rotation

Which of these is an example of erosion?

• Light shining onto a mountain.
• Rain breaking down rocks on a mountain into smaller pieces. 
• Wind blowing away sediment to a new place on the mountain.
• All of the above.

What is an enormous mass of ice moving over land, causing weathering of rock and soil?

• A glacier
• An iceberg
• An ice wedge
• A sand dune

How do plants weather rocks?

• Plants don't weather rocks.
• When roots grow into cracks of rocks and expand the rock breaks.
• When the plant moves water from the roots to the leaves, the rock breaks.

The process of carrying away weathered bits of rocks is called

• weathering
• erosion

Wind blowing sand from one location to another is called

• Weathering
• Erosion
