Across
  1. 6. a loop of moving fluid in which the motion results from differences in density caused by differences in temperature
  2. 7. boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other
  3. 8. movement of a gas or liquid in a definite direction
  4. 9. the part of the earth's interior beneath the crust and above the central core
Down
  1. 1. process by which heat moves efficiently through air or water
  2. 2. the process of heat transfer by the bulk movement of molecules within fluids such as gasses and liquids
  3. 3. the movement of continents resulting from the motion of tectonic plates
  4. 4. long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another.
  5. 5. a rigid layer of the Earth's crust that is believed to drift slowly
