3. running along the Mid Atlantic Ridge, was discovered by Maurice Ewing and Bruce Heezen in 1953
6. when one plate sinks into the mantle underneath the other plate
7. the movement of two oceanic plates away from each other
9. a process that occurs at mid-ocean ridges
10. theory explaining the movement of the Earth's plates
13. the deepest parts of the ocean floor

1. theory which states that parts of the Earth's crust slowly drift atop a liquid core
4. location where two tectonic plates meet
5. when two tectonic plates slide past one another
8. a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithospere
11. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas
