\n– Alluvial fans are fan-shaped deposits of sediment formed at the base of a mountain or at the mouth of a narrow valley where a stream flows onto a flatter surface, characteristic of mountain foothills.
\n– ‘V’-shaped valleys are formed by the erosional action of rivers in their upper course, typically found in mountainous areas where downcutting is dominant.
\n– Deltas are landforms created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or standing water, usually the sea or a lake. They are characteristic features of the lower reaches of rivers, often found at coasts.
\n– Ox-bow lakes are crescent-shaped lakes formed in abandoned meander loops of a river, typically found in the flat, alluvial plains of the river’s lower course.
