GENERAL GEOLOGY

Detailed explanation-1: -One of the two ways minerals form is by: 1. crystallization of magma (cools inside the crust) or lava (cools & hardens on the surface) 2. crystallization of materials dissolved in water. When these liquids cool to a solid state, they form crystals.

Detailed explanation-2: -There are basically two different ways in which crystals can form. One of these is from a molten liquid in the case of the crystallization of magmas or lavas. The other way is the deposition from a solution, much in the same way that salt water creates salt crystals as the water evaporates.

Detailed explanation-3: -Minerals can form in three primary ways being precipitation, crystallization from a magma and solid-state transformation by chemical reactions (metamorphism).

Detailed explanation-4: -Explanation: One way that minerals form is when lava or magma cools and hardens to form crystals. (Crystallization is the process of atoms forming a material with a crystal structure.) An example of this process is the creation of amethyst.
