How is the size of the mineral grains affected by the rate at which molten rock material cools?

Answers

Answer 1
Answer:

The rate at which molten rock material cools affects the size of the mineral grains. The longer it cools, the larger the crystals become.

What is mineral?

  • A mineral is a naturally occurring substance that has distinct chemical and physical properties, composition, and atomic structure.
  • An economic mineral is a broader term that includes minerals, metals, rocks, and hydrocarbons (solid and liquid) extracted from the earth through mining, quarrying, and pumping.
  • A mineral exists as inorganic element or compound that occurs naturally and has an orderly internal structure as well as a distinct chemical composition, crystal form, and physical properties.
  • Quartz, feldspar, mica, amphibole, olivine, and calcite are examples of common minerals. Minerals are elements found on the earth and in foods that our bodies require for normal development and function.
  • Calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium are all necessary for good health.
