Science

1. stress that pushes a mass of rock in two opposite directions
6. the pattern of lines by an earthquake
8. move more slowly than p waves and s waves
10. a single number that geologists assign to an earthquake based on its size
11. seismic waves that compress and expand the ground like an accordian
12. the rocks on either side of the fault slip past each other sideways
13. the stress force that pulls on the crust and things rock in the middle
14. a large area of flat land elevated high above sea level

2. the point on the surface directly above the surface
3. the fault cuts through rock at an angle so one bloc of Rick sits over the fault
4. the area beneath the Earth's surface where rocks are under stress
5. the stress force that squeezes rock until it folds or breaks
7. has the same structure as a normal fault but the blocks move in the reverse direction
9. seismic waves that can vibrate from side to side
12. an instrument that records and measures an earthquakes seismic waves
