I hope that helps you

Answer 2

Answer:

Try it!Research on the different kinds of minerals found in common products (e.g. lipstick, glass) that you use every day. What do you think?Is there a possibility for the physical characteristics of rock minerals to change over time? Explain your answer.Key PointsA mineralis a naturally occurring, inorganic, solid material that has a fixed structure and a definite chemical composition. Minerals can be identified based on their physical and chemical properties. Useful physical properties to identify a mineral include color, streak, luster, specific gravity, hardness, cleavage, tenacity, and crystal habit. The chemical properties of minerals depend on their chemical formula and crystal structure. Solubility and melting point are chemical properties commonly used to describe a mineral. The most common rock-forming minerals are quartz, feldspar, mica, pyroxene, amphibole, and olivine. The most reliable way to identify a mineral is by using a combination of several tests.
