define meanders,oxbowlakes and delta
Answers
Explanation:
Meander :- meander means a winding curve band of a river or road.
Delta :- Delta is an area of low, flat land shaped like a triangle, where a splits and spreads out into several branches before entering the sea.
Explanation:
meander is a winding curve or bend in a river. Meanders are the result of both erosional and depositional processes. They are typical of the middle and lower course of a river. This is because vertical erosion is replaced by a sideways form of erosion called LATERAL erosion, plus deposition within the floodplain.
b) An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water. This landform is so named for its distinctive curved shape, which resembles the bow pin of an oxbow.
c) A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.
