Across
  1. 3. ocean crust colliding with ocean crust
  2. 5. the gradual movement of the continents across the earth's surface through geological time.
  3. 6. having high concentration of particles in one object or space
  4. 7. a mountain range in Asia (home to the highest peaks)
  5. 8. thick part of Earth's crust that is more complex than oceanic crust
  6. 9. where two tectonic plates come together and collide
  7. 10. ocean crust colliding with continental crust
  8. 16. a long narrow excavations in the ground
  9. 17. molten material beneath or within Earth's crust
  10. 18. natural elevation of Earth's surface that rises abruptly (usually taller than 2000 feet)
  11. 19. coming violently into contact
Down
  1. 1. a row of islands that come from a particular line of volcanoes
  2. 2. having low concentration of particles in one object or space
  3. 4. collision of the Earth's crustal plates which results in one plate being overridden by another
  4. 11. relatively young part of the Earth’s crust that underlies the ocean
  5. 12. the two sub-layers of the earth's crust (lithosphere) that move, float, and sometimes fracture and whose interaction causes continental drift, earthquakes, volcanoes, mountains, and oceanic trenches
  6. 13. sudden violent shaking in the ground
  7. 14. a chain of 14 volcanic islands in Alaska
  8. 15. 4,500 mile stretch of mountains along the western coast of South America (world’s longest mountain range)
