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

Option (C)

Explanation: When the molten magma under the earth's crust becomes cool, it then solidifies and forms crystals, by the process of crystallization.

This minerals then combines to form rocks, and the rocks that are formed by the crystallization of magma is known as the igneous rocks. For example, granite, rhyolite.

Rocks are the aggregates of minerals. Common examples of some minerals are olivine, pyroxene, amphibole and feldspar.

Thus, the correct answer is option (C).

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
