  2. the layer of rock between the Earth's crust and core
    mantle
  3. the central part of the Earth below the mantle
    core
  4. the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
    lithosphere
  5. the soft layer of the mantle on which the tectonic plates move
    asthenosphere
  6. the strong, lower part of the mantle between the asthenosphere and the outer core
    mesosphere
  7. a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
    tectonic plate
  8. the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
