The Short Answer

Evaporation is a special type of vaporization where the water molecules are simply breaking free from the rest of the liquid, despite being below the boiling point temperature. The sun heats the surface layer of water molecules and the molecules may occasionally bounce out and escape the forces that attract them to each other and rise into the air as *vapor. There’s just so munch buzzing and bouncing between molecules that when the sun heats them up and they’re moving just right, they can pop off and rise into the air. It also cools the liquid it leaves behind. Edit: a word, thank you /u/pacofuentes
