Which low-lying landform is described as areas that catch water from rivers or hollows that dip into a central point and are surrounded by higher ground?

• A. Basins
• B. Valleys
• C. Deltas
• D. Ridges

Answer: (A)

Understanding basins as bowl-shaped, low-lying areas that collect water from the surrounding land is the key idea. A basin is bordered by higher ground on all sides, forming a hollow where rainfall and runoff flow toward a central point. That central low area often gathers water to form a lake or a stream outlet, which matches the description of catching water from rivers or hollows that dip inward. Valleys are low areas but they’re usually elongated and not necessarily enclosed by higher ground on all sides. Deltas form at river mouths from sediment buildup, not from a central catchment. Ridges are raised crests, not depressions that hold water. So this landform best fits the concept of a basin.
