Answer: Increase in compactness of the material.
Explanation:
Evaporites are the sedimentary rocks that are formed by the sediments and brines of the materials being degraded or withered from the parent and pre-existing rocks. The water is also lost from the withered material due to evaporation. The borax and gypsum also lose water to become evaporites and the increase in compactness due to loss of water molecules and increase in intramolecular forces between solid substances in the rock helps in sedimentation of the rock.
