Because the silt in the sea has salt in it
river is fresh water because it has no salt in it. ocean is salt water because of its salt content. hope this helps
An estuary is the place when river water mixes with seawater (salty ocean water).
The Pacific Ocean is salty, there is no fresh water in it.
The place where a river flows into an ocean and fresh water mixes with salt water is known as a delta. The water that is less salty than seawater is known as brackish water.
running river water
The Avon River is fresh water.
All rivers are by definition fresh water unless they are very polluted. There is, however, a portion of every river that reaches an ocean that is called an estuary. this is where the fresh water coming downstream mingles with the salty tidal water of the ocean.
Sea water is salty, and river water is fresh.
It's fresh water. The salt remains in the oceans as the water evaporates.
Ocean water Can't drink it and its salty. Fresh Water can drink it, because its fresh :D!
This would depend if the water is from a sea or a river source.
