  1. 3. Spots that are particularly hot in the mantle. They can melt the lithosphere and for volcanoes. They are referred to as mantle plumes.
  2. 6. Part of the cause of mountains changing. It is the breaking down of rocks on the Earth's surface.
  3. 8. What do you call the process of an oceanic plate sliding under a continental plate?
  4. 9. Tectonic plate boundary where two tectonic plates slide away from each other. This creates crust.
  5. 11. The thickest layer of the Earth that creates convection currents.
  6. 14. Tectonic plate boundary where two tectonic plates slide past each other in opposite directions.
  7. 15. The very center of the Earth with two layers (inner and outer).
  8. 17. The thinnest layer of the Earth that holds all of the plates on which the continents and the ocean rest.
  9. 19. The hottest part of the mantle that is in between the lithosphere and the lower mantle.
  10. 20. A break in the Earth's crust.

  1. 1. Tectonic plate boundary where two plates crash into each other.
  2. 2. Where the edge of plates meet.
  3. 4. Deep holes underwater, formed from Oceanic-Oceanic Convergent Boundaries.
  4. 5. Liquids in the Earth that move tectonic plates.
  5. 7. They are formed from plate tectonics pulling apart creating a crack in the Earth.
  6. 10. Part of the cause of mountains changing. It is the movement of the sediments from where they were.
  7. 12. The part of the Earth that is made up of the upper mantle and the crust.
  8. 13. Things that float on the mantle and are the crust of the Earth broken up into many pieces.
  9. 16. A sudden movement of sediments caused by gravity, such as a landslide.
  10. 18. Large-scale uplift.
