Weathering and Erosion

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

A cliff formed near the ocean.  Which statement best describes how this cliff formed?

• Warm air melted the rock.
• Sun rays evaporated the rock.
• Ocean waves washed away rock.
• Plant roots pushed away the rock.

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

• Erosion
• Landslide
• Weathering

• An iceberg
• An ice wedge
• A sand dune

Weathering and erosion are the same thing.

• True
• False

Which of the following is NOT a type of chemical weathering?

• water
• carbon dioxide
• ice wedging
• living organisms secreting acid to break down rocks

What is erosion?

• The process by which
  water, ice, wind or gravity
  moves fragments of rock
  and soil.
• The process by which
  water, ice, wind or gravity
  deposit rock sediments
  and soil in a new place.
• The breaking down of
  Earth’s crust into smaller
  and smaller pieces.

What is deposition?

• The process by which
  water, ice, wind or gravity
  moves fragments of rock
  and soil.
• The process by which
  water, ice, wind or gravity
  deposit rock sediments
  and soil in a new place.
• The breaking down of
  Earth’s crust into smaller
  and smaller pieces.

Which of the following is NOT a type of physical weathering?

• burrowing plants
• ice wedging
• plant roots
• acid rain
