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

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

• Erosion
• Landslide
• Weathering

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.

What is the wearing away or breaking down of rocks called?

• Weathering
• Erosion
• Glaciers

Weathering and erosion are the same thing.

• True
• False

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.

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.
