Evaporating the water salt is obtained; but rivers concentrations of sodium chloride are low and the method is not economical.
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.
There is the same amount of salt that goes out of the water to the salt that comes in the water so that is how it remains balance. Actually the oceans are slowly getting more and more salty, due to dissolved salts from the land in river water.
YES. A thermocline is a sudden change in the temperature of the water. A halocline is a sudden change in the salinity of the water. A pycnocline is a sudden change in both. The warmer, fresh water will advance to the top of the water, and the cold, salty water will stay at the bottom. Since there are two factors effecting this, pycnoclines happen to be more distinct.
The ocean serves as the major source for evaporation of water back into atmospheric circulation. At the poles, they are also a source of fresh water as sea ice, but this does not contribute significantly to the production of water resources.
3% of the world is made of fresh water
No. Fresh water is simply water that is not noticeably salty.
Only about 10 of the water that evaporates from a salty ocean is fresh water.
No they cannot, its why they're so called.
not all water on earth is fresh its 60% fresh and 3% salty
The body of water in Egypt that has both fresh and salty water is where the River Nile flows into the Mediterranean Sea. The fresh water from the Nile mixes with the salty Mediterranean water, creating a barrier between the two.
Fresh water filled.
The Pacific Ocean is salty, there is no fresh water in it.
Salty. They are made out of salt water.
Ocean water Can't drink it and its salty. Fresh Water can drink it, because its fresh :D!
Most of the water on earth is salt water.
Fresh water is evaporated faster.
No way.... not possible, it has to be seprated with salty water, if u mix fresh water with the salty one the whole thing will become salty ........... dont u know ? when u mix salt in water the whole water gets salty.... but yea u can take out salt out of the water and make it fresh... the process in science known as "Distillation" to seprate salt from the water....
