Across
  1. 2. The rigid outer part of the earth, consisting of the crust and upper mantle.
  2. 5. The action or process of changing in shape or distorting, especially through the application of pressure.
  3. 11. A geologic process in which tectonic plates split apart from each other.
  4. 12. A system of ideas intended to explain something.
  5. 14. The point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
  6. 16. An area on Earth where two or more lithospheric plates collide.
  7. 18. A planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.
  8. 21. Outermost shell of a terrestrial planet.
  9. 22. A current in a fluid that results from convection.
  10. 23. A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
  11. 24. A linear feature that exists between two tectonic plates that are moving away from each other.
Down
  1. 1. The process by which the North pole is transformed into a South pole and the South pole becomes a North pole.
  2. 3. The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
  3. 4. A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
  4. 6. The place inside Earth's crust where an earthquake originates.
  5. 7. Boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other.
  6. 8. What happens to the crustal material on either side of a fault during an earthquake.
  7. 9. Mostly solid bulk of Earth’s interior.
  8. 10. The mantle in the region under the lithosphere and the asthenosphere, but above the outer core.
  9. 13. A fault along a plate boundary where the motion is predominantly horizontal.
  10. 15. Extremely hot center of Earth, another planet, or a star.
  11. 17. The upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
  12. 19. The movement of continents resulting from the motion of tectonic plates.
  13. 20. Huge and irregular slabs of rock into which the lithosphere of the earth is broken.
