What kind of river is a tributary?

A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.

What are rivers fed by?

Most rivers begin life as a tiny stream running down a mountain slope. They are fed by melting snow and ice, or by rainwater running off the land. The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be called a river.

What is an example of a tributary river?

What is an example of a tributary? An example of a tributary is the Missouri River. Although it is a mighty river in its own right and at the heart of its own watershed in the northern United States, it flows into the Mississippi River near St.

Which is the opposite of a tributary or distributary?

A confluence, where two or more bodies of water meet together, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. Distributaries are most often found in river deltas .

How is a tributary different from a mainstem?

Tributaries. A tributary is a river or stream that enters a larger body of water, especially a lake or river. The receiving water into which a tributary feeds is called the “mainstem,” and the point where they come together is referred to as the “confluence.” Each tributary drains a different watershed into the mainstem,…

Why are the tributaries of a river important?

Cumulative pollution from a river’s tributaries contributes to unsafe habitats and drinking water, a factor exacerbated by proximity to developed areas. Although tributaries feed into larger water bodies, they themselves are often of substantial size and frequently named as rivers.
