Question

Crescent shaped lakes formed by rivers are called _____.

a) Moon lakes b) Oxbow lakes
c) Horseshoe lakes d) Crescent lakes

Answer 1

The correct answer is option d) Crescent lakes.

Steep curves formed by rivers are called meanders. Due to the alternate deposition and erosion at the sides, a meander sometimes becomes so pronounced that it eventually cuts off from the main river. The cut off water body looks like a crescent and is called an oxbow lake.
