What are three ways that minerals can be identified

Igneous minerals crystallize from molten rock, metamorphic minerals are recrystallized from other minerals without melting, and sedimentary minerals precipitate from water and, sometimes, from air.

Explanation:

Minerals have various ways in which they can form. Molten rock crystallizes the igneous minerals. Other minerals crystallized again the Metamorphic minerals without melting, and water precipitates the sedimentary minerals and, sometimes, from the air.Most minerals can be classified by their unique physical properties. The physical properties include hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
