Plate Tectonics

2. a tectonic boundary where plates crash into each other.
6. fault that blocks move in opposite directions
7. measure of the energy released by an earthquake
8. in an earthquake, the point beneath Earth's surface where energy release occurs
9. point of Earth's surface directely above an earthquake's focus
10. a tectonic plate boundary where plates move past each other.
12. single large landmass made up of all the continents connected together that broke apart 200 million years ago
13. a break in the earths crust
14. A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates.
15. theory that Earth's crust and upper mantle are broken into sections that move around on a plastic-like layer of the mantle

1. fault that cuts through rock at an angle so one block of sits over the rock
3. stress force that pulls the crust and thins rock in the middle.
4. A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates.
5. large area of flat land elevated high above sea level.
11. fault that slips each other sideways with little up or down motion.
