Explain
(i) Oxbow lakes
(ii) Meanders
Answers
Answer:(i) An oxbow lake is a U-shaped lake formed when a wide meander of river is cut off in its lower course. (ii) A meander is a loop made by a river in its lower course.
Explanation:
Meanders are formed in the lower course when the river, loaded with debris, becomes very slow. The river swings from side to side as it flows over a level tract, forming winding sections or loops. Continuous erosion on the concave side and deposition on the convex side can cut a loop from the main river and lead to the formation of an oxbow lake.

HEY MATE!! HOPE IT HELPS U
Explanation:
An oxbow lake is a U-shaped lake that forms when a wide meander from the main stem 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.
A meander is a winding curve or bend in a river. 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.
