Estuary
An estuary.
Rivers, streams, the Atlantic Ocean and other normal water sources.
Streams join together to become rivers. Then the water from the rivers and streams will eventually run into the ocean or a lake.
Rivers or Streams
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".
Runoff
Confluence is the joining of two water flows (rivers, streams) into a single stream.
salt is formed in the sea by water from rivers and streams washing salt from the ground into the ocean.
Well, groundwater and runoff both land on Earth as precipitation, but groundwater is water that gets trapped underground by seeping through rocks. You capture this water by wells. Runoff is when precipitation flows from (usually) mountains. The water gets into streams, and streams join to form rivers. The rivers would usually lead to the ocean. Most of the runoff gets evaporated when the water reaches the ocean; only a little-bit of the water in rivers and streams flowing down is evaporated then.
Natural springs are not a means of water erosion. Some types of water erosion include rain, streams, rivers, and ocean waves.
