Here's why:
* Evaporation: As seawater evaporates, the concentration of dissolved salts increases.
* Precipitation: When the water becomes sufficiently concentrated, the dissolved minerals start to precipitate out of solution, forming crystals.
* Accumulation: These crystals accumulate over time, forming layers of sedimentary rock.
Common examples of evaporites include:
* Halite (rock salt): Formed from the precipitation of sodium chloride (NaCl).
* Gypsum: Formed from the precipitation of calcium sulfate dihydrate (CaSO₄·2H₂O).
* Anhydrite: Formed from the dehydration of gypsum.
* Sylvite: Formed from the precipitation of potassium chloride (KCl).
