Rivers By: M. Sandhu
A watershed is an area of ridge of land that separates water flowing to different rivers, basins, or seas.
A source is the original point of which a river flows. It might be a river or a lake. This is where a stream starts.
A delta is a land form that forms a mouth of a river.
A great basin is no drainage to the river
Headquarters are rivers that flow to the mouth
Divide is to separate rivers
A down river is the point or near the mouth
Tributary is a stream or river that flows into the same mainstream.
