What is a U shaped bend in a river that gets cut off from the main river?
Correct Answer
C. Oxbow
Explanation
An oxbow is a U-shaped bend in a river that gets cut off from the main river. Over time, due to erosion and deposition, the bend becomes more pronounced until it eventually becomes a separate body of water, known as an oxbow lake. This process occurs naturally as rivers meander and change their course over time. The formation of oxbow lakes is a common occurrence in river systems and can be observed in various parts of the world.
