Which term describes the deposition of material after erosion occurs?

• A. Erosion
• B. Transportation
• C. Sedimentation
• D. Ejection

Answer: (C)

Deposition happens when eroded material settles out of the moving medium after erosion has removed it from its original location. This settling is called sedimentation—the process of laying down sediment as energy from water, wind, or gravity decreases. When the transporting medium slows, its capacity to carry particles drops, causing particles to drop out and accumulate, forming sediments such as river bars, deltas, or layered deposits. Erosion is the removal phase, transportation is the moving phase, and ejection isn’t the standard term used for this sequence.
