7. B - Ridge push and slab pull. the force of gravity makes the ridge to push on the lithosphere that is farther from the ridge. Slab pull motion is caused by the tectonic plate subduction.
8. B - continental drift
9. D - rift valley. For divergent boundaries, these may include rift valleys with thick sedimentary sequences.
10. D - shear. The three tyres of stress that act on Earth's rocks are compression, tension, and shear.
11. D - seismic risks.
12. A - along the ocean floor.
13. C - two oceanic plates converge. When two oceanic plates collide one oceanic plate is eventually subducted under the other.
14. B - nonexplosive, producing large amounts of lava.
15. C - pancaking. Means to collapse one floor after another.
16. D - seismometer.
17. B - fault. Earth doesn't just move but a fault causes it to move.
18. D - the removal of mass from the crust causes the crust to rise.
19. B - surface waves. The type of wave in an earthquake that will cause the most destruction is a surface wave and a seismic wave.
20. C - convergent and divergent boundaries.
