What is sedimentation?

What is sedimentation?

• A. The process by which eroded soil particles in water or air are deposited in NEW locations.
• B. The dissolution of minerals in water.
• C. Soil detachment by wind energy.
• D. The settling of fines in soil pores.

Answer: (A)

Sedimentation is the process of particles that are suspended in a fluid—water or air—settling out and being deposited when the carrying flow slows down or loses energy. This is exactly what happens when eroded soil particles are transported and then drop out to form new deposits in different locations. The other statements describe different processes: dissolution is minerals dissolving in water, erosion by wind is the detachment and removal of soil rather than its deposition, and settling of fines in soil pores refers to movement inside the soil structure rather than deposition from an external transport medium.
