Sediment is transported by which agents?

Sediment is transported by which agents?

• A. Wind, rivers, glaciers, and humans
• B. Only rivers
• C. Only wind
• D. Only glaciers

Answer: (A)

Sediment transport happens through several agents, depending on the environment and the energy in play. Flowing water in rivers moves sediment in various ways: some particles ride along as bedload, others stay suspended in the moving water, and dissolved material can be carried downstream as well. Wind can lift and move fine sands and dust, especially in deserts and on beaches, reshaping dunes and spreading sediments over large areas. Glaciers transport sediment by carrying it within the ice itself and by routing meltwater that deposits sediments far from their source. Humans also act as transport agents—construction, farming, mining, and dam-related activities disturb soils and relocate sediment across landscapes and into waterways. Because all of these pathways contribute to moving sediment in different settings, this broader view is the most accurate.
