Across
- 3. a quick volume expansion associated with an exceptionally violent outward release of energy, typically accompanied by the development of high temperatures and the emission of high-pressure gases.
- 6. a type of solid precipitation
- 7. numerous types of mass wasting that can encompass a wide range of ground motions.
- 11. shaking of the Earth’s surface caused by a sudden release of energy in the Earth’s lithosphere
- 12. a powerful ground-level wind system that originates from an above-ground point source and blows radially
- 14. a cenote, swallet, swallow hole, or doline, is a depression or hole in the ground created by surface layer collapse.
- 17. a type of storm distinguished by the presence of lightning and its acoustic effect on the Earth’s atmosphere, known as thunder.
Down
- 1. a powerful columnar vortex that forms over a body of water.
- 2. an outpouring of water that submerges ordinarily dry ground.
- 4. a unusual sort of natural disaster in which dissolved carbon dioxide erupts unexpectedly from deep lake waters, generating a gas cloud capable of drowning wildlife, cattle, and humans.
- 5. a fast-moving flow of snow down a slope, such as a hill or a mountain.
- 8. a widespread, long-lasting straight-line windstorm associated with a fast-moving cluster of severe thunderstorms
- 9. line of thunderstorms that forms along or ahead of a cold front. It includes heavy rain, hail, frequent lightning, strong straight-line winds.
- 10. a blaze that becomes so large that it generates and supports its wind system.
- 13. a severe snowstorm with sustained winds of at least 56 km/h that lasts for an extended time—typically three hours or more.
- 15. a period of chronic deficits in water supply, whether from the atmosphere, surface water, or subsurface water.
- 16. a violently rotating column of air that collides with the Earth’s surface
