Which of the following depositional landforms is formed at the mouth of a river where it enters a standing body of water and drops its sediment load?

💡 Solution & Explanation

A delta is a major depositional landform created at the mouth of a river where flowing water enters a standing water body like a sea or lake, causing a sudden reduction in velocity and consequent dropping of sediments. Landforms such as alluvial fans form at the foothills of mountains where streams emerge onto flat plains rather than directly into standing water bodies. Deltas are exceptionally fertile regions that support dense agricultural populations worldwide.
