Across
  1. 4. Plate boundary where two plates are moving apart
  2. 7. When one plate slides under another at a convergent plate boundary
  3. 8. Large pieces of the Earth’s crust that move on top of the mantle
Down
  1. 1. Crust that is denser, thinner, and newer, will subduct at oceanic-continental convergent boundaries
  2. 2. mainly at convergent and divergent plate boundaries and is the result of hot gasses, magma plumes, and pressure
  3. 3. that is less dense, thicker, and older
  4. 5. Result of tectonic plates moving past each other typically at transform and convergent plate boundaries
  5. 6. Plate boundary where two plates slide past each other
  6. 8. result of a stationary magma plume from inside the mantle that creates island or mountain chains
  7. 9. Plate boundary where two plates are moving together
  8. 10. form of divergent plate boundary where new ocean floor is made
