  • LITHOSPHERE- UPPER PART OF MANTLE MADE UP OF A ROCK CALLED PERIDOTITE (MORE IRON AND MAGNESIUM)
  • MESOSPHERE "LOWER MANTLE"- MUCH THICKER THAN UPPER MANTLE. MADE OF MAGMA ROCK THAT IS SO HOT IT TURNS TO LIQUID. IT IS ALSO STIFF BECAUSE IT'S UNDER GREAT PRESSURE
  • MANTLE- LARGEST LAYER OF EARTH DIRECTLY BELOW CRUST. 1800 MILES DEEP AND MADE UP OF SILICON, OXYGEN AND MAGNESIUM
  • ASTHENOSPHERE- SOFT PLASTIC LIKE ROCK. HEAT MAKES THE ASTHENOSPHERE FLOW LIKE TAR (LAVA THAT COMES OUT OF A VOLCANO)
