The solid mineral material forming part of the earth surface.


  • Formed from cooling and solidification of magma or lava.
  • Formed above and below the earths surface.
  • There are extrusive rocks that cool very fast on the earths surface and there are intrusive rocks that cool very slowly under the earths surface.


  • Formed when sediment is deposited out of air.
  • Formed on the earths surface.
  • Organic which form by the accumulation of plant or animal debris and chemical which form from the precipitation of minerals from water,


  • Chemically changed due to different temperatures and pressures.
  • Formed deep beneath the earths surface.
  • Non-foliated rocks are formed around igneous intrusions and foliated rocks are also formed the same way.


  • Formed in the earths crust
  • Glassy, and the crystal size is small
  • Vesicular
  • Black, density is 1, composes gabbro, olivine, and plagioclase.


  • Inorganic
  • Clastic, grain size is less than 0.0004
  • Composes mostly quartz,feldspar, and clay minerals
  • Compact, may split easily

Anthracite Coal

  • Non-foliated
  • Fine grain size
  • Composes carbon
  • Regional metamorphism
  • Metamorphism of bituminous coal
