Minerals crystallize from solutions primarily through evaporation, where the dissolved substances become concentrated until they form solid crystals. Another method is through heated water solutions that cause minerals to precipitate as they cool. Both processes result in the formation of mineral crystals. ;
Minerals crystallize primarily through evaporation of water solutions or from heated water solutions. As water evaporates, minerals become concentrated and form crystals, while heating can change solubility, leading to crystallization upon cooling. Therefore, the correct answer is B. from solutions that evaporate.
