This document contains 10 questions about minerals and answers the questions. It tests knowledge about the definitions of minerals, including that minerals must be inorganic, form repeating crystalline patterns, and can form through crystallization of magma. It also covers hardness of common minerals on the Mohs scale such as diamond, quartz and talc. The questions assess understanding of how minerals form inside the Earth and on its surface.
