Which term refers to sediments deposited by a river?

• A. Alluvium
• B. Source
• C. Ox Bow Lake
• D. Plunge Pool

Answer: (A)

Sedimentary deposits laid down by flowing water settle when a river loses enough energy, often on floodplains and riverbeds. The term for this material is alluvium, which includes silt, sand, clay, and gravel carried by the river and deposited as it slows or overflows its banks. This makes alluvium the best description of sediments deposited by a river. The other terms refer to different river features or origins: a river source is where the river begins, oxbow lake is a cutoff bend forming a lake, and a plunge pool is an erosional feature at the base of a waterfall. They are not names for sediments deposited by a river.
