They form in mountains and flow through mountain river valleys. *** b. •As water or wind slows down, it has less energy and can hold less sediment, which can result in some of the sediment being deposited. This is called moraine. Glaciers deposit their sediment when they melt. •Sediment is deposited in locations called depositional environments, such as swamps, deltas, beaches, and the ocean floor. When snow accumulates, the snow above exerts a lot of pressure on the snow below, which triggers it to recrystallize and transform into solid ice. What are 3 ways that rocks can be deposited? groundwater can cause an erosion through a process called chemical weathering.Carbonic acid flows into cracks in the limestone.Then some of the limestone is carried away in a solution of water.This process hollows out pockets in the rock that will form caves or caverns. scrapes underlying rock. 7.
