Across
- 4. occurs between two colliding plates, one subducting underneath the other, whereby convection currents in. the upper mantle suck both plates open
- 5. act against the driving forces of plate tectonics.
- 7. force resists movement of lithospheric plates.
- 8. occurs when a heavy plate is pulled into the mantle but resists subduction because of friction.
- 9. occurs when the lithosphere is pushed up by the asthenosphere because of convection currents from the mantle.
Down
- 1. is the force that resists all the forces associated with plate movement in subduction zone.
- 2. caused by the rising of heat from the core toward the mantle.
- 3. is the frictional force due to the opposing movement of plates moving past one another between two spreading centers.
- 6. takes place when a subducting slab sinks into the hot mantle because of a difference in temperature.
