Question

Quizplus · Accepted Answer

Floodplain deposits are primarily composed of fine-grained sediments such as silts, clays, and muds that are deposited during floods as water slows down over the flat land surface. These sediments are usually rich in organic materials, making them fertile soils for agriculture. While some gravel and sand may also be deposited, they are not the primary components of floodplain deposits. Bedload transport and braided streams may contribute to floodplain deposits, but they are not the only factors.
