Where does a stream begin?

The source of a river or stream is the original point from which the river flows. ... The source is the farthest point of the river stream from its estuary or its confluence with another river or stream. Rivers are usually fed by many tributaries. The farthest stream is called the head-stream or head water.

Explanation:

All rivers and streams start at some high point. ... As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. These streams may slowly join together to form a larger stream or river. Small rivers and streams may join together to become larger rivers.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
