What is the process called when sediment is laid down in the landscape as the energy of the transporting force decreases?

• A. Erosion
• B. Deposition
• C. Weathering
• D. Transportation

Answer: (B)

Deposition is the process of sediment being laid down in the landscape when the energy of the transporting force decreases. As a river slows, wind loses strength, or meltwater and ice lose their capacity to carry material, the sediments settle out of the flow. Heavier particles drop first, with finer material following, building up features like river deltas, floodplains, beaches, dunes, or moraines in glaciers. Erosion involves removing material, weathering is the breakdown of rocks in place, and transportation is simply the movement of sediment by an agent—deposition is the stage where that material is finally deposited.
