Rivers and Streams

From outer-space, the earth looks like it is covered with veins and arteries, similar to our bodies. The earth's arteries, however, are really a vast web of rivers and streams that channel water across the planet, from mountains to oceans. 

Although there are many rivers and streams, these sources of running water account for a very small portion of the earth's total surface, just .3%.
