Across
- 2. a graphical illustration of seismic waves a disturbance moving energy from one place to another without transferring matter.
- 4. A steep-sided volcano formed from erupted andesitic and rhyolitic lava along convergent boundaries.
- 6. A small, steep-sided volcano that erupts gas-rich basaltic lava.
- 7. A vent in the Earth's crust in which magma flows.
- 10. Molten rock stored below Earth's surface.
- 11. Location on Earth's surface directly above an earthquake's focus.
- 14. Energy traveling on and in Earth as vibrations.
- 16. A measurement of liquid's resistance to flow.
- 17. A loction where olcanos form far from plate boundaries
- 18. magma that erupts onto the Earth's surface.
- 19. A volcano with gentle slopes of basaltic lava, common near divergent boundaries and hot spots.
Down
- 1. Instrument measuring the ground's motion to determic how far seismic waves travel.
- 3. Seismic wave causing particles to move at a right angle relative to where the wave travels.
- 5. Location in earth where rocks first move along a fault where seismic waves originate.
- 8. tiny particles of pulvurised volcanic rock and glass
- 9. A crack in the Earth's lithosphere along which movement occurs.
- 12. Seismic wave where particles in the ground move in a push-pull relationship similar to a slinky.
- 13. Seismic wave that causes things on the ground to move up and down in a rolling motion.
- 15. vibrations caused by ruptured and suddenly moving rocks along a break or crack in the Earth's crust
