Question

which process forms salt beds?
deposition
cementation
evaporation
lithification

Explanation:

Salt beds form when water evaporates, leaving behind salt crystals. Deposition is the laying down of sediment. Cementation is the binding of sediment particles. Lithification is the process of turning sediment into rock. Evaporation is the key process for salt bed formation as it removes the water, concentrating the salts.

Answer:

evaporation
