Weathering, Erosion, and Deposition
By: Carson Poulos
Weathering is the breaking and changing of rocks. It breaks big rocks into smaller rocks, soil, and sediment. It is caused by water, wind, ice, change in temperature, plants, expansion, and contraction.
Erosion is the picking up of weathered rock, soil, and Earth's materials and transporting them. Erosion is caused by water movement, wind, ice, gravity, and people. A form of erosion is creep.
Deposition is the depositing of eroded rock. Deposition is caused by water movement, wind, ice, gravity, and people. Deposition builds new landforms everyday. For example, rocks weather turning into sand, which gets blown away in a storm. It piles up on a ridge forming a sand dune. The depositing of the sand to form a sand dune is the deposition.
