Answer:
C. Rivers wear away banks until the bank is broken and the river flows straight.
Step-by-step explanation:
- The Oxbow lakes mostly form during the period of a flood. the water of the river is looking for the swiftest and the most directed route so instead of flowing around the meander it cuts through straight across it and flows.
- Oxbow lakes start as a meander during a flood and form the new channel. the water in it becomes stagnant for a long time and forms a lake until the water in it gets dry out.
