Sediment can be classified based on which criterion?

Sediment classification based on whether it is eroded or deposited material provides a clear understanding of its origin and role in the sedimentary process. Eroded material refers to particles that have been worn away from their original location and transported by wind, water, or ice, while deposited material has settled or accumulated in a new location after being transported. This classification helps in understanding sediment dynamics, including processes of erosion, transportation, and deposition, which are fundamental to managing sediment in environmental and engineering contexts.

In contrast, classification based on color and texture, type of geological formation, or supersaturation of minerals does not directly address the processes that create or move sediment. While these factors can provide additional insights into the characteristics and composition of sediment, they do not reflect the fundamental distinction between the states of sedimentation critical for erosion control and management practices. Thus, focusing on whether sediment is eroded or deposited provides a more actionable framework for effective sediment management strategies.
