Answer:
Oxbow lake is formed when a bend in a river is cut off to form a lake.
Step-by-step explanation:
- OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .
- OPTION B - It is formed when a bend in a river is cut off to form a lake.
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
- OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.
This statement is also wrong, as a river delta is specified by this statement.
- OPTION D - It is formed when a dam stops the flow of a river and creates a lake.
This statement is also false, since the creation of a reservoir is established by this statement.
FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , the correct option is B.
