Minerals like halite and gypsum often form from evaporation. This occurs when 1. when water evaporates, some of it turns into minerals if it bumps into rocks on the way up.

2. mineral molecules dissolved in water evaporate with the water, forming tiny mineral crystals in the clouds that fall back to earth when it rains.

4. mineral molecules dissolved in water turn solid when the water becomes very hot.
