Answer 2

Identify rock-forming minerals using their physical and chemical properties S11/12ES-la-9.

• Chemical characteristics like solubility and melting point are frequently used to define minerals. The minerals quartz, feldspar, mica, pyroxene, amphibole, and olivine are those that create rocks the most frequently. Combining numerous tests is the most accurate technique to identify a mineral.
• Feldspar, quartz, amphiboles, mica, olivine, garnet, calcite, and pyroxenes are some of the minerals that create rocks.
• Color, hardness, lustre, crystal formations, density, and cleavage are characteristics that aid geologists in determining a mineral's identity in a rock. The atomic structure of a crystal essentially determines its form, cleavage, and hardness. Chemical composition is the main determinant of colour and density.
• Learning Competencies & Code: Determine the physical and chemical characteristics of common rock-forming minerals. S11/12ES-Ia-9
• We walk on, construct on, and cultivate gardens on rock-covered land. Mineral-based compounds make up all rocks in the world. A mineral is an inorganic solid that forms in nature and has an organised atomic structure and a known chemical composition. This may sound a little complicated at first, but after you break it down, it gets clearer.
