Streams join together to become rivers. Then the water from the rivers and streams will eventually run into the ocean or a lake.
Rivers, streams, the Atlantic Ocean and other normal water sources.
Rivers or Streams
The water that flows in streams and rivers into the ocean and lakes is called runoff or freshwater.
a body of water that can lead to the ocean.
It is usually the other way round. Moving in the direction of water flow, streams merge together to form larger rivers, the streams are called the river's tributaries. The point of joining is called a "confluence".
When two streams join together, it is called confluence. This natural phenomenon occurs where two rivers or streams meet and merge into a larger body of water.
Runoff
salt is formed in the sea by water from rivers and streams washing salt from the ground into the ocean.
Rivers and rain are the two that I can think of.
