2. A great flowing or overflowing of water, especially over land not usually submerged.
5. A localized, violently destructive windstorm occurring over land, especially in the Middle West, and characterized by a long, funnel-shaped cloud extending toward the ground and made visible by condensation and debris.
8. A brief powerful eruption of particles and intense electromagnetic radiation from the sun's surface, associated with sunspots and causing disturbances to radio communication on earth.
10. Outward and downward slope movement of an abundance of slope-forming materials.
12. A period of dry weather, especially a long one that is injurious to crops.
15. Asteroids that impact the Earth.
16. A transient storm of lightning and thunder, usually with rain and gusty winds, sometimes with hail or snow, produced by cumulonimbus clouds.
17. A storm with hail.

1. Expulsion of magma and gas from the Earth's interior.
3. A heavy and prolonged snowstorm covering a wide area.
4. An air mass of high temperature covering an extended area and moving relatively slowly.
6. A large-scale, atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion.
7. An unusually large sea wave produced by a sea quake or under sea volcanic eruption.
9. Occurs when a gas, usually CO2, suddenly erupts from deep lake water.
11. Caused by natural erosion or human mining makes the ground too weak to support the structures built on it.
13. The result of a sudden release of energy in the Earth's crust that creates seismic waves.
14. Any large fire that spreads rapidly and is hard to extinguish.
