Answer:
c) A drainage divide is a ridge that separates one watershed from another.
Step-by-step explanation:
As part of the hydrological cycle, when precipitation occurs on a mountain the water will flow on the side it lands on. Each side will lead the water into different drainage basins. Drainage basins are divided by physical mountain barriers, a drainage divide. The water will flow in along the surface, soil flow, groundwater, and in a river channel to the mouth of a river.
