Across
  1. 2. A huge piece of the lithosphere that moves with the asthenosphere. The movement causes earthquakes and volcano's.
  2. 4. The thickest layer of the earth between the crust and the core. It has hot moving rock the slowly circulates.
  3. 5. The part of earth's crust that forms land. It's thicker but lighter then the Oceanic crust.
  4. 7. The rigid outer layer of the earth, made of the crust and upper mantle.
  5. 10. The edges where the tectonic plates meet. This is where earthquakes and volcanoes often happen.
  6. 11. A place where maggma rises from deep inside the earth, forming volcanos. Hawaii was created by a hot spot.
  7. 12. The liquid layer around the inner core also made of iron and nickel. Creates a magnetic field.
  8. 13. The crust under the ocean, thinner but heavier then the Continental crust.
  9. 15. Something melted due to extreme heat, like lava from a volcano.
  10. 17. The thin, outermost layer of the earth where we live. It's like the skin of an apple.
  11. 18. A place where two plates push together. it can form mountains or volcanos like the Andes.
  12. 19. A tectonic plate under the ocean. it's thinner but denser then Continental plates.
Down
  1. 1. deep valley in the ocean floor, formed when one plate sinks under another. The Mariana trench is the deepest one.
  2. 3. A large piece of the earth's crust that carry's land. These plates move slowly.
  3. 6. A place where two plates move apart. It can create new ocean floor, like the mid-atlantic ridge.
  4. 8. The soft, flowing layer of the mantle below the lithosphere allowing techtonic plates to move
  5. 9. A place where two plates slide past each other, causing earthquakes, like the san Andreas fault line.
  6. 14. The solid super hot center of the earth, made of mostly iron and nickel. Like a metal ball in the earth.
  7. 16. The invisible force around earth that protects us from the suns radiation. It makes a compass point north.
