Minerals can form deep inside earth’s crust by a. cleavage and fracture. b. friction along faults. c. crystallization of melted materials. d. evaporation of ancient seas.

The correct answer that would best complete the given statement above is option C. Minerals can form deep inside earth's crust by the crystallization of melted materials. There are two ways on how minerals are formed: crystallization of melted materials and the crystallization of materials dissolved in water. Hope this helps!

c. crystallization of melted materials

Explanation:

A mineral is composed of the various rock-forming crystals and hee crystals tend to recrystallize through the process of evaporation and the deposition of sediments that are bought and deposited from within the earth and these make up most of the constituents of the crustal rocks. As they are naturally occurring in a pure form. There physical and chemical properties also plays an important role in the formation of crystal of the mineral. The hardness, opacity, and color are all dependent on the inorganic and organic constituents of the rocks.

It’s either c or d as the answer.
