Plate Boundaries

2. divergent, convergent, and transform
8. openings, or vents where lava,small rocks and steam erupt onto the Earth's surface.
9. molten rock that is underground
12. a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge
13. break apart or become separated through faulting caused by plate tectonics
14. mountain range separating the plains of the Indian subcontinent from the Tibetan Plateau
16. where the cold oceanic lithosphere sinks back into the mantle and is recycled
17. two tectonic plates that are moving away from each other

1. tectonic plates slide horizontally past each other
3. slab of solid rock, generally composed of both continental and oceanic lithosphere
4. of fire a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes
5. molten rock that breaks through the Earth's surface
6. any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks
7. slab of solid rock, generally composed of both continental and oceanic lithosphere
10. Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.
11. continental transform fault that extends roughly 1,200 kilometers through California
15. two or more lithospheric plates collide
