The process of sediment accumulation over time is called?

• A. Sedimentation
• B. Erosion
• C. Weathering
• D. Precipitation

Answer: (A)

Sedimentation is the process by which sediment settles out of a transporting medium and accumulates in layers. As particles carried by water, wind, or ice lose enough energy, they settle to the bottom and build up over time. This gradual buildup forms sedimentary layers, which can later be compacted and cemented into sedimentary rocks. Erosion is the removal of material, weathering is the breakdown of rocks in place, and precipitation is the formation of droplets or solids from a solution—none of which describe the accumulation of sediment itself.
