GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Tributary is a stream or river that flows and joins the larger river.

Detailed explanation-3: -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.”

Detailed explanation-4: -A river is a large stream of water flowing through the land, usually fed by smaller streams.

Detailed explanation-5: -The end of a river is its mouth. Here, the river empties into another body of water-a larger river, a lake, or the ocean. Many of the largest rivers empty into the ocean. The flowing water of a river has great power to carve and shape the landscape.
