Across
  1. 4. a resisting force that resists all the forces associated with plate movement in subduction zones only
  2. 6. a resisting force that works on all parts of a moving plate
  3. 7. occurs when a heavy plate is pulled into the mantle but friction resists it; directly opposes the slab pull
  4. 8. a driving force that occurs between two plates where one subducts beneath the other and convection currents suck both plates down
Down
  1. 1. happens when newly-formed lava along the ridge pushes the plates to either side
  2. 2. happens when hot mantle material rises upward to the Earth's crust and as it cools, it becomes denser and sinks
  3. 3. a resisting force that happens when two plates move past one another
  4. 5. occurs when a subducting plate sinks into the mantle due to the difference in temperature and density
