Across
  1. 5. consists of the crust, upper mantle and where the plate tectonics are located.
  2. 6. boundary: when 2 plate tectonics meet or collide with each other.
  3. 7. found at the ocean floor where a boundary occurs creating a long, and slim opening in the seafloor.
  4. 8. ridge: a divergent boundary occurs at the sea floor creating mountain ranges that which create new crust.
  5. 10. the collection of the continental was all one, making a massive super continental.
  6. 11. Tectonics: located in the lithosphere and moved by the asthenosphere creating geological features above and underground.
  7. 13. Plate: denser but thinner than the continental plate.
  8. 14. boundary: when 2 plates slide beside each other.
Down
  1. 1. when an oceanic plate slides under a continental plate due to its thinness.
  2. 2. plate: thicker but less dense than the oceanic plate.
  3. 3. boundary: when 2 plates move or drift apart from each other.
  4. 4. vents: on a divergent boundary which formation has the characteristics or elements of extreme pressure, extreme heat, nutrient black smoke and on the ocean floor.
  5. 6. Drift: a hypothesis stating that the earth's continental or its surface was moving.
  6. 9. spreading: the spreading of magma from a mid-ocean ridge and its cooling creating new crust.
  7. 12. Wegner: the person who hypothesized continental drift theory.
