How is a watershed related to a river system

The stream mouth is where a waterway streams into a bigger waterway, for example, another stream, a lake, or a sea. A watershed limit, likewise called a seepage isolate, marks the external most point of confinement of a watershed. A watershed is a tract of land depleted by a waterway and its tributaries.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
