Question

Define water divide.

Answer 1

A drainage divide, water divide, divide, ridgeline, watershed, or water parting is the line that separates neighbouring 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.

Answer 2

Continental divide in which waters on each side flow to different oceans (such as the Congo-Nile Divide)Major drainage divide in which waters on each side of the divide never meet but flow into the same ocean (such as the divide between the Yellow River basin and the Yangtze, another, more subtle, example being the Schuylkill-Lehigh divide at Pisgah Mountain in Pennsylvania in which two minor creeks divide to flow and grow east and west respectively joining the Lehigh River and Delaware River or the Susquehanna River and Potomac River, with each tributary complex having separate outlets into the Atlantic.)
