Earth’s structure and materials2

  1. 1.  The layer of solid rock that makes up the Earth’s outer layer including the continents and the ocean floor.
  2. 2.  A dark, fine-grained extrusive volcanic rock that makes up the oceanic crust.
  3. 3.  A light colored, coarse -grained volcanic rock that makes up a large part of the continental crust.
  4. 4.  The layer of rock found below the crust that is separated into the lithosphere, asthenosphere, and mesosphere.
  5. 5.  The uppermost part of the mantle composed of brittle rock and the crust of the Earth.
  6. 6.  The less rigid part of the mantle directly underneath the lithosphere.
  7. 7.  The lowest part of the mantle that is made up of semi-liquid rocks.
  8. 8.  Outer layer of the core made up of dense, liquid metal.
  9. 9.  Center layer of the core made up of solid metal.
  10. 10.  The crust that forms the continents which is made up of many different types of rocks but mostly granite.
  11. 11.  The crust that lies beneath the oceans which is made up of basalt.
  12. 12.  Heat from the core is transferred by convection into     the mantle. The heat causes convection currents in the mantle and core. Convection currents have been moving inside Earth for more than 4 billion years. Convection currents in the mantle cause the tectonic plates to move. Convection currents in the core cause the Earth’s magnetic field.
