Question

identify common rock forming minerals using their physical and chemical properties.​

Answer 1

Explanation:

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.

Answer 2

Identify common rock forming minerals using their physical and chemical properties.​

• The chemical composition and crystal structure of minerals determine their chemical characteristics. 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.
• Feldspar, quartz, amphiboles, mica, olivine, garnet, calcite, and pyroxenes are some of the minerals that create rocks.
• Most minerals have distinct physical characteristics that can be used to identify and categorise them, including hardness, lustre, colour, streak, specific gravity, cleavage, fracture, and tenacity.
• Numerous features can be used to identify minerals. These include crystallography, electrical conductivity, magnetism, radioactivity, and fluorescence, as well as physical and chemical traits including hardness, density, cleavage, and colour.
• The mineral olivine is quite hard, typically pale green, and found in squat crystals. It is a typical mineral found in igneous rocks with dark colours. In the Earth's mantle, olivine is the mineral that is most prevalent.
• The five most prevalent minerals found on Earth are olivine, quartz, feldspar, and mica (including hornblende-type amphibole). The most often utilised minerals are copper, platinum, silver, gold, cobalt, platinum, aluminium, and lithium; some of these are not frequently "used" in daily life.
