  1. Zone the process by which one tectonic plate sinks below another, returning to the mantle, where the rock is re-melted. Subduction takes place at convergent plate boundaries. Oceanic crust, which is denser, will always subduct under the less dense continental crust. It is also the process in which slab pull occurs.

  9. A usually light colored igneous rock that is found in continental crust
  10. Spreading the process by which new oceanic crust is formed when magma rises up through fissures and solidifies at the mid-ocean ridges and thus pushing the older, adjacent seafloor towards trenches. This is why the age of the sea floor increases with distance away from the mid-ocean ridges.
