GEOLOGY

Detailed explanation-1: -A line which separates two adjacent drainage basins is known as water divide.

Detailed explanation-2: -Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water–lakes, streams, reservoirs, and wetlands–and all the underlying groundwater. Larger watersheds contain many smaller watersheds.

Detailed explanation-3: -A drainage divide, water divide, divide, ridgeline, watershed, or water parting is the line that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges and maybe in the form of a single range of hills or mountains, known as a dividing range.

Detailed explanation-4: -A drainage divide separates the area tributary to a particular stream from the area’s tributaries to adjacent streams.

Detailed explanation-5: -A drainage divide separates each drainage basin from other drainage basins. Drainage basins can range in size from a few km2, for small streams, to extremely large areas, such as the Mississippi River drainage basin which covers about 40% of the contiguous United States (see figure 17.5c in your text).
