If rain is caused by convection air currents over the oceans, sucking up sea water.why is Rainwater not salty?

Answer 1

it doesn't really 'suck up' seawater. Rain is caused by moist air mixing with cold air, causing the moisture in moist air to condense. The moisture is water vapor. This could be over oceans or land.
Now there could be some trace amounts of salt in water droplets but there could also be trace amounts of soot particles or other air pollution. Can't tell whether it's there unless you have very sensitive instruments to test for it.

Answer 2

The reason rain water isn't salty like sea water is because most of the salt ions in the ocean are far too heavy to evaporate in sufficient amounts to affect the taste of the rain water. It's the principle behind growing crystals actually. You take a container of salt water and let it sit in a place where it's not going to be jarred too much and leave the lid off of it. In a few days or even weeks, you'll have salt crystals inside of the container, all crystals form by water carrying ions which when combined with the appropriate matching ions it'll create the crystals be it salt, quartz, fluorite, etc. by the water evaporating. The slower the evaporation the larger the crystals become, the faster the smaller they are. H2O is much lighter than NaCl in it's molecular weight. H2O = 10 amu's and NaCl = 28 amu's. So the lighter compounds are more likely to evaporate, leaving the heavier ones behind, though the water that evaporates does carry with it the Na+ and Cl- ions within them. The elements are in very small amounts though, so you wouldn't notice them at all if you tasted the raindrops.

Answer 3

You might have studied about distillation process by which impurities are removed from a liquid by evaporating it and condensing it so as to get a pure form of the liquid.Similarly rain water is also obtained by a natural distillation process, i.e. evaporation, condensation and precipitation.That is why rain water is sometimes(not always as impurities in the air sometimes dissolve in it while falling as in the case of acid rain) considered as pure water.
So rainwater is not salty as salt is removed during evaporation.

Answer 4

When the ocean or sea is heated by the sun tiny particles of water vapor are pulled into the air. The water vapor is so small that the salt stays behind. Once the water vapor condenses in the atmosphere fresh water falls from the sky!

Tada!!

Answer 5

Salt does not evaporate, so as the evaporation takes place, only the water will go away. Put water and salt in a ban and boil out the water. The salt will always stay in the pan.

Answer 6

yea, the sun evaporates the water in the ocean, but the salt stays in the sea, so rainwater isnt salty.

Answer 7

The liquid water is converted into water vapor. That vapor is pure H2O. The salt and impurities don't evaporate and you are left with water vapor in the clouds. This is the water cycle

Answer 8

because the sea WATER evaporates, not the salt - it stays in the sea

Answer 9

"cause when water evaporates, The salt stays in the sea...
