Rivers usually start as a small body of water, known as a stream, that runs and <u>flows down a mountain or a hill</u>. If the right and optimal conditions are met, <u>rains starts falling and feeds different streams that eventually meet and form an individual and larger body of water known as a large channel or gully</u>.
This body of water <u>grows larger as it continues to be fed by rainwater and snow melting (depending on the location) and becomes a </u><u>river</u>. Once multiple rivers are formed, they empty out into the ocean.
