Choose the best description of how this calcite was formed.

• Magma cooled slowly below the surface of the Earth forming large crystals.
  
• The mineral went through tremendous heat and pressure     inside the Earth forming layers of grains.
  
• Sediments dissolved in water creating a solution which evaporated leaving the crystals behind.
  
• Lava cooled very quickly on the surface forming no crystal     structures.
