GEOLOGY

Detailed explanation-1: -A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range.

Detailed explanation-2: -A watershed starts at the highest points on the landscape, like mountain peaks and ridgelines that divide one valley or drainage from another. The imaginary line that connects those high points is called the watershed divide.

Detailed explanation-3: -The boundary between drainage basins is a drainage divide: all the precipitation on opposite sides of a drainage divide will flow into different drainage basins. A drainage basin provides a limited surface area within which physical processes pertinent to the general hydrology may be considered.

Detailed explanation-4: -A line which separates two adjacent drainage basins is known as water divide. Contours showing a ridge are elongated and are closely spaced. The side on which the ridge is steeper, the contours are drawn closely together, whereas the side on which the ridge is gentle, the contours are drawn far apart.
