(7.MS-ESS2-2) 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.
