The smaller stream is a tributary of a larger stream, river or lake.
Tributary
Every river is part of a larger river system which includes the river and any tributaries that branch off of it.
It is called a tributary.
The Uruguay River and the Negro River ("Black River"). The first one is the longest (around 1,100 miles) and from where country takes its name and the second one is the one with a larger flow.
Tributaries are streams that flow into one primary river. A tributary can also flow into another stream or a lake.
The join of a small river (a tributary) joins a larger river (the main river) is called a confluence.
It is not. It is the other way round, a stream or smaller river flowing into a larger one.
It Joins at a confluence. That is where the river joins the larger one.
A small stream or river that flows into a bigger one is called a "tributary." Tributaries contribute water to the larger river, enhancing its flow and ecosystem. They can vary in size and length, and their junctions often create diverse habitats for wildlife. Ultimately, tributaries play a crucial role in the hydrological system and the overall health of riverine environments.
A small river or stream is not called a river basin. A river basin is a portion of land drained by a river and it's tributaries. It encompasses all of the land surface dissected and drained by streams and creeks that flow downhill into one another, and eventually into one river.
Where two rivers meet is called a confluence.
No, because a delta is usually at the end of a river [leading out] a tributary feeds water into a river.
