Earth's Changing Surface

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.

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

• physical 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.

• physical weathering

• chemical weathering

• erosion weathering

• deposition
