In what two ways can substances dissolved in water eventually form minerals?

Substances dissolved in water can form minerals through two primary processes: evaporation and precipitation. In evaporation, water gradually loses volume due to heat, concentrating the dissolved substances until they reach a saturation point, leading to crystallization of minerals. In precipitation, when the concentration of certain ions in the water exceeds their solubility, they combine to form solid mineral crystals that settle out of the solution.
