What is meant by a water divide? Give an example.
A mountain or an upland separates two drainage basins in an elevated area. Such an upland is known as a water divide.
For example, Ambala is located on the water divide between the Indus and the Ganga River.
Though the Indus, the Sutlej and the Brahmaputra rivers rise very close to each other near the Mansarovar Lake but because of the water divides they flow in different directions.
