Across
- 2. caused when materials are compressed, bent, or stretched and return to original shape
- 4. erupted materials
- 5. lava reaches the surface by traveling through this tube-like structure
- 6. the point of failure where waves originate
- 10. a fracture or system of fractures along which Earth moves
- 11. total force acting on crustal rocks per unit of area
- 12. composed of layers of lava from non-explosive eruptions and materials that pile around the vent after an eruption
- 13. small volcanoes with steep slopes; composed of materials of materials that pile around vent after an eruption
- 14. smallest pieces of erupted materials
- 15. along this type of boundary rock is squeezed causing reverse faults to form; earthquakes can be very strong and deep
Down
- 1. resistance to flow
- 2. the point on the earth's surface directly above a focus
- 3. along this type of boundary a normal fault will form; earthquakes tend to be shallow because crust is thin
- 4. along this type of boundary shear stress pushes plates in opposite directions; earthquakes are relatively shallow
- 7. large volcanoes with gentle slopes; composed of layers of lava from non-explosive eruptions
- 8. large depressions that form after the magma chamber empties
- 9. lava emerges through this opening
- 12. bowl-shaped depression around the vent of a volcano
