Sedimentation in AP Environmental Science

Definition

Sedimentation is the process by which particles settle out of a fluid (such as water) and accumulate at the bottom over time. It occurs when suspended particles become too heavy to remain in suspension and sink down due to gravity.

Erosion:

Erosion refers to the wearing away and removal of soil or rock materials by natural forces such as wind, rain, or flowing water.

Deposition: Deposition happens when eroded sediments are dropped or laid down in a new location, often due to a decrease in the speed or energy of the transporting agent (e.g., water or wind).

Turbidity: Turbidity is a measure of how cloudy or murky water appears due to the presence of suspended particles. High turbidity levels can indicate increased sedimentation.
