Why does fresh water has more or less dissolved salts than seawater?

Salt or sodium chloride one is a metal poisonous and the other is gas poisonous to humans but combined is beneficial t humans. A very long time ago the seas were not salty . Salt comes from the earth as a solvent element when rains washes it eventually to the seas as consequence the seas are getting saltier and saltier .

Why is it correct to say seawater is a mixture?
Because seawater is made up of many elements that can be seperated.
What is the solute and solvent of seawater?
The solvent of sea water is obviously water and the solute is salt...
How is magnesium obtained from seawater?
When fresh water is removed from ocean water, the salts that are left behind are also a valuable resource. Over half of the world's supply of magnesium, a strong, light metal, is obtained from seawater in this way.
What is dissolved in seawater?
water, salt and urine
Which water will freeze faster salt water or fresh water?
Fresh water will freeze faster than salt water, and at a higher temperature too. Why?Salt water is called salt water due to its containing dissolved salts -- usually Sodium Chloride (NaCl), but any other salts will do. When water freezes, the molecules link up into a crystal structure (ice). The atoms of any dissolved salts will interfere with the formation of the crystal, meaning more energy will have to be taken out (the temperature will have to drop lower) before salt water freezes.
What is the matter of seawater?
Sea water is water with a few thousand different dissolved salts and a variety of dissolved or suspended organic compounds.
The accumulated salts in seawater make the seawater much more dense than fresh water One of the characteristics of salt water is that it has?
A lower freezing point than fresh water
Is seawater is mixture?
yes
Is ground water salt water?
groundwater can be fresh, or can have various salts and/or minerals dissolved in it
What are the materials needed to obtain fresh water from seawater?
It will need a Reverse Osmosis membrane to filter out salts from the water.
How is the sea water purified into drinking water in United Arab Emirates?
The process is called desalinisation. There are a few processes, but the main ones is done by heat. It involves taking seawater (which is water containing dissolved salts). Heating the seawater to boiling point and allowing, the pure water evaporates as steam, the steam is collected and condensed back into fresh water. The dissolved salts cannot evaporate become concentrated as "brine", this concentrated salt water is then pumped back into the sea, and the fresh water pumped to consumers. Most emirates use natural gas (which is abundant in the region) to heat the water to boiling point.
What percentage of 100mls of seawater is pure water?
It varies depending on what part of the ocean it is measured. Approximately 96.5% of seawater is water. The rest is dissolved salts. See related link for more information.
Does fresh water cointain no dissolved salt?
"Fresh" water contains all types of salts including sodium chloride, and calcium chloride. Only distilled water contains no salts, it is pure H2O

Where would you find the lowest density in seawater?
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.

Because seawater is made up of many elements that can be seperated.
