  • Winds move small particles of dust through the air and larger particles of sand along the ground.

  • Ice, in the form of glaciers, transport rock and soil particles as they move downhill.



Deposition is a natural process of

  • Deposition is a natural process of

  • laying down or depositing sediment in new
