Which term describes sediment originating from continental erosion and river transport?

• A. Terrigenous Sediment
• B. Silt
• C. Siliceous Ooze
• D. Active Sonar

Answer: (A)

Sediments are classified by their source. The term for material that originates from continental erosion and is transported to the ocean by rivers is terrigenous sediment. This type comes from weathered rocks on land and is carried into the sea by rivers, wind, and glaciers, forming particles from clay to gravel that accumulate along continental margins. Silt describes a grain size rather than origin, so it doesn’t name the source on its own. Siliceous ooze is a biogenic deposit formed from the silica shells of organisms, not from land erosion. Active sonar is unrelated to sediment types. So the correct term for sediment from continental erosion and river transport is terrigenous sediment.
