• Weathering
• Erosion
• Deposition

____________ is the breaking of rock into smaller pieces

• Weathering

Why does a delta form at the mouth of a river?

• because the water becomes more salty at the mouth?
• because the river becomes faster and drops its sediment.
• Because the river becomes slower and drops it sediment.
• becasue the river is more narrow at the mouth.

  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.
