Across
- 2. a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system
- 6. energy that travels as vibrations on and in Earth; there are three types of seismic waves: primary waves (P waves), secondary waves (S waves), and surface waves
- 7. a large volcano with gentle slopes of basaltic lava that is common along divergent plate boundaries and oceanic hot spots
- 9. a rotating column of water and spray formed by a whirlwind occurring over the sea or other body of water
- 10. tiny particles of pulverized volcanic rock and glass
- 13. molten rock below Earth’s surface
- 15. a fast-moving wave of seawater caused by seismic activity in oceanic plates
- 16. the point on the Earth’s surface directly above where an earthquake originates
- 18. a liquid’s ability to flow
- 19. a small, steep-sided volcano that erupts gas-rich, basaltic lava
Down
- 1. a volcano that is not associated with plate boundaries
- 2. a storm with thunder and lightning and typically also heavy rain or hail
- 3. a vent in Earth’s crust through which melted--or molten--rock flows
- 4. a severe snowstorm with high winds and low visibility
- 5. the point within the Earth where an earthquake originates
- 8. a vibration in the ground that results from movement along breaks in the Earth’s lithosphere
- 11. molten rock that erupts onto Earth’s surface
- 12. a storm with a violent wind, in particular a tropical cyclone in the Caribbean
- 14. a break in the Earth’s lithosphere where tectonic plates meet
- 17. a large, steep-sided volcano that results from explosive eruptions and andesitic and rhyolitic lava and ash along convergent plate boundaries
