rain comes from clouds, clouds are formed by the evaporation from the sea, the sea contains salt

During the evaporation of water from the sea, the salt is left behind in the sea, so the water vapour is just pure water...no salt in it.
The water vapour rises in the atmosphere to form clouds, condensation of water vapour occurs into water droplets and then precipitated as rain.
Thus rain water is not salty.

Rain is evaporated water from oceans and rivers and bodies of water around the globe. When water heats up and begins to evaporate, the salt content of the water, being heavier, does not evaporate with the water into the atmosphere. Hence, when it rains, the water that comes down is fresh water.

Rain Water comes from Water on the ground evaporating. Salt is to heavy to evaporate and remains on the ground.

Because during the vaporation the salt in the sea water is left behind. You may do this experience boiling some water in a coffee pot with a lot of salt. With a plate you can stop some water steam which leaves the coffee pot by the spout. After this you may taste the water on the plate. you will noticed that the water is saltless.

The salt is too heavy to be evaporated with the water, water goes salt stays....OK.

Oh now this question takes the biscuit.
Try evaporating salt. I suggest you take a really good book while you wait.

the water evaporates due to the heat of the sun.it condenses in atmosphere to form water droplets.so the salt does not evaporate.only water can evaporate....thats why it rain water has no salt......

It's called distillation. Seperation due to evaporation.

such like above said. and also relate about boiling point.
boiling point of salt is 1465°C (2669° F) and water is 100 °C.
that's why it's pure evaporation.

You have answered your own question. Did you not learn at school what evaporation was?
