Rock Facts
  • Metamorphic rocks are rocks that have changed from one form to another.
  • These rocks form deep in the earth where the it is very hot and there is a lot of pressure.
  • If a rock is heated and squeezed for millions of years, it can turn into a new kind of  rock.
  • Metamorphic rocks begin to form at 12-16 kilometers (7.5 - 10 miles) beneath the surface of the earth. (Use this site to convert kilometers to miles)
  • They begin changing at temperatures of  100 - 800 degrees Celsius (212 - 1472 degrees Fahrenheit) (Use this site to convert kilometers to miles
  • The heat in the earth comes from Magma and the pressure comes from layers of rock piled onto layers of rock.
  •  The layers on the bottom get squeezed and the thicker the layers the more pressure or the more they get squeezed.
