Deposition is the geological process in which sediments, soil and rocks are added to a land form or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
Weathering wears away or changes the appearance or texture of (something) by long exposure to the air.
Erosion can carry rocks and sand away to build new land.
The ocean basin is the flattest part in the ocean.
