when you mix these two elements together they make a solid. DUH! since in water the molocules are less titley packed than the ones in the salt they go together. think of it this way: the molocules in the water kind of "learn" from the molocules in the salt. GOOD LUCK!

It doesn`t.
Salt is a solid ,water a liquid - salt is only soluble to a certain extent in cold water.Once you reach this threshold you can`t dissolve any more hence the appearance of a solid.
Heat the mixture and it dissolves better since the water molecules are further apart.

Huh?
If you add salt and ice it turns the ice to a liquid but can reduce its temperature right down to -17.5degC, which is 0degF which is how Anders Farenheight came to his zero value. I've done it myself, it's most impressive.
Salt reduces the temperature at which water freezes and I've managed to keep water liquid, though saturated to below -5degC. Now that's cold if you wiggle your finger in it.
I don't know where you got your idea from but it's definitely in error. The ancient Greeks thought that the truth could be achieved simply by discussion. Modern science does it though experimentation. We may not be perfect but we're getting better.

It doesn't when you mix it, if however you boil/evaporate off the water you will be left with the solid salt crystals.

I don't see it come. I think when you add water to salt (more salt than water) then you have a solid mixtures. But salt to water no (more water than salt).

Are you talking about supersaturated solution?
This is an unstable solution containing a greater concentration of solute than is present in a saturated solution. Such a solution deposits the excess solute if a crystal of the solute is added to it.
It is prepared by dissolving solute at one temperature and carefully changing the temperature to a point where the solution is unstable.
Does this help?

Does it?
I've never noticed.
Salt has always dissolved in water for me.
until it becomes a saturated solution anyway.

It doesn't. And it's 'a' solid, not an solid.

it doesn't
it just makes saltwater- (ie the ocean)

because it crystallises again
