Soil Erosion and 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

What is weathering?

• 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.
