Water gets into the atmosphere by evaporation. When water evaporates, mineral content it may have had (salt and other minerals) is left behind. The water that falls as rain is pure with no mineral content.

Because salt doesn't evaporate, water does.
However, some of the particles that rain drops form around are (very small) salt crystals that have become airborne through various means (winds blowing across salt flats, waves pounding against a rocky shore line, etc).

When the sun shines down on the ocean and evaporates the water on the surface, it is in effect distilling the water. The pure water vapor is then carried over land where it mixes with cooler air and condenses back into water.

Everyone is correct about salt not evaporating. In fact my son did an experiment. He put a bowl of salt water in front of a window, and sure enough, only the salt was left in the bottom of the bowl.

The salt doesn't evaporate. ~
Same reason that the water doesn't get mixed into the alcohol, when it is being distilled. The heavier, less volatile materials stay behind.

Because evaporated water can't hold salt in solution.

when the water evaporates only pure water evaporates not salt water

because salts don't go with water as it evaporates
