Minerals can be defined as inorganic substances that can be found naturally on earth. There are more than 3,000 different types of minerals. Quartz is the most common mineral that exists naturally on the earth. It always contains two oxygen atoms for one silicon atom. Rocks are formed when two or more types of minerals combine together. Mineral crystals are so small that they can be viewed under the microscope only. All the minerals are inorganic as they are made of non-living particles. They are always solid and have a crystalline structure.

Quick Facts: –

  • The size of mineral crystals depends on the rate at which magma cools down. When it cools at a slow rate, large crystals are produced and when it cools at a higher rate, smaller crystals are produced.
  • The human body uses minerals to perform different functions like strengthening bones, transmitting nerve impulse etc.
  • Usually, a mineral is made up of just one chemical element but sometimes, it could be a mixture of two or more.
  • Mohs scale of hardness is used to measure the ability of minerals to scratch each other.
  • There are two different types of minerals macro minerals and trace minerals.
  • Olivine is a type of mineral that is generally used to cast aluminum objects.
  • Feldspar can be defined as a very large group of minerals that are extremely abundant on earth.
  • The density of a mineral is defined as its Specific Gravity (SG).
  • The branch of science that includes the study of minerals is known as mineralogy and the person who studies it is known as a mineralogist.
  • The minerals required by the human body are different from the minerals found on the earth.
