why is rain water not salty when it comes from salty sea water?

Answer 1

Basically the salt is left behind when the water evaporates. When I was on holiday in Ibiza I passed the salt flats they have there and felt pretty silly because I never knew they collected salt like that. They have acres and acres of shallow basins and let sea water in to them. They then shut off the sea coming in and let the water evaporate and they are left with a solid crust of salt that they harvest.

Answer 2

Anyone who has spent sometime on a beach in a hot climate will notice that evaporation caused by action of sun's heat is not total. Lower layers of the earth near the sea is still salty and as the water vapour keeps rising it becomes less and less salty. When eventually the water vapour reaches the clouds it is not salty at all and becomes semihard. and crystalline. When the clouds gets cooled after a while from a combined action of wind and heat the clouds melt into tiny droplets and these follow the pull of gravity. Result -full fledged downpour ' We then call it RAIN. Does this help?

Answer 3

Cause water evaporates from the sea and leaves the salt behind in the sea!!
due to this rain water is not salty even though it comes from the sea water that is salty...

Answer 4

It is because water on the surface of the sea evaporates leaving the salt still in the sea, have you ever done an experiment at school with a saline solution, when you boil it in a conical flask the salt is left behind and forms new crystals while the steam can be condensed back into water simply by hitting a cold surface just like in the hydrological cycle (in the atmosphere where the air is thinner).

Answer 5

Try this at home!

put some salt into a glass and add tap water. Allow to dissolve and leave this solution on a tray near a window. The window is not a specific location, but will help speed up observations.

What happens - water vapour is constantly leaving the solution and merging into the surrounding air. When the salt is all that remains, it follows that the water has all gone into the air.

This is a simple mimic of what happns at sea. Water evaporates, rises into clouds and deposits on land MINUS the salt. This is because SALT does not evaporate.

Answer 6

Actually, much of the rain that falls near a coastline
has salt in it. Salt is an excellent nucleus for water
vapor to form a rain drop on. However, since a lot of
water is contained in a raindrop, it dilutes the salt
nucleus to the point that it's hard to tell that there
is salt in the drop. The rain drop is not nearly
as salty as seawater.

When water evaporates from the oceans, the salt is left behind. There are
lots of microscopic salt particles in the atmosphere however, as water
droplets from waves evaporate. These same salt particles become
condensation nuclei for raindrops and snowflakes. The salt quantity in the
raindrops is so small that the raindrops are considered fresh water. There
are other kinds of condensation nuclei besides salt particles, such as
dust, volcanic ash, even ice crystals, and other chemical particles that
attract water vapor.

Answer 7

When water evaporates, the solids remain behind. Heating up salt water will not cause the salt in the water to become a vapour. So only the water itself is evaporating, and eventually returning to earth as rain drops.

Answer 8

Sea water gets to the clouds by evaporation. This leaves the salt behind in the ocean. Rain falls in the rivers, which wash more salt into the sea. Thus, in theory, the sea gets saltier.

Answer 9

Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere, and makes clouds

the salt crystals is left behind on earth, they are not carried up into clouds

Answer 10

sea water is salty cus it contains salt. during the evaporation, only water evaporates, not the salt molecules in water. the water vapour (without salt) then form cloud and u get saltless rain.
