Which term describes the fertile, flat area that is regularly flooded by a river?

• A. Flood Plain
• B. Levees
• C. Interlocking Spurs
• D. Load

Answer: (A)

The concept being tested is the floodplain, a broad, flat area next to a river that is regularly flooded. It forms from repeated floods that deposit sediments called alluvium, which makes the soil very fertile and ideal for farming. The flat, low-lying surface is created by these ongoing deposits, and the regular floods help maintain that flatness. Levees are raised banks that constrain floods rather than define the flat land itself. Interlocking Spurs are features formed in the upper valley by erosion, not the floodplain. Load refers to the material carried by the river, not the landform. So the fertile, regularly flooded area beside a river is the floodplain.
