Across
- 2. Dissolved gases in a volcano
- 4. A mixture of hot volcanic ash, coarser particles, and steam that pours at high velocity down the flank of a volcano
- 5. This effect is due to rotation of Earth from west to east under a fluid such as the atmosphere or oceans permits that fluid to lag behind Earth’s rotation
- 7. A section of an active fault that has not had a recent earthquake
- 8. The third in a sequence of seismic waves of an earthquake; it travels near Earth’s surface and causes large ground motions
- 11. A particularly strong rotating thunderstorm that can spin off dangerous tornadoes
- 12. A mechanism to isolate a structure from earthquake shaking in the ground; often flexible pads between a building and the ground
- 15. The rotating area of cloud that sags below the main thundercloud base and from which a tornado may develop
- 17. Modifying existing buildings to minimize the damage during a strong earthquake.
- 19. An abnormally long wavelength wave most commonly produced by sudden displacement of a large mass of water in response to fault movement on the seafloor
- 21. Fires ignited by firebrands which blow through the air ahead of the main fire
- 23. The high-speed stream of air current traveling, generally in meanders, from west to east across North America
- 25. The small-diameter core of a hurricane; characterized by lack of clouds and little or no wind
- 26. Forest fuels of different heights that permit fire to climb progressively from burning ground
- 27. Lava that spills out of a volcano and flows down its sides
- 29. This effect is created when moisture-bearing winds rise against a mountain range: They condense to form clouds and rain or snow
- 30. The percentage of moisture in air relative to the maximum amount it can hold (at saturation) under its given temperature and pressure
- 32. A flow of mud, rocks, and water dominated by clay or mud-sized particles
- 33. Burning embers carried by the wind, which have potential to ignite new fires
- 34. Restriction of development according to practical and ethical considerations, including the risk of natural hazards
- 35. The rapid sea-level rise caused by the strong winds of a storm that push water forward and to a lesser extent by the low atmospheric pressure of a major storm
Down
- 1. The theory applied to most earthquakes in which movement on two sides of a fault leads to bending of the rocks until they slip during an earthquake to release the bending strain
- 3. A fire that burns into the treetops
- 6. Convergent boundary along which lithospheric plates come together and one descends beneath the other
- 9. The theory that lithospheric plates move relative to one another
- 10. Changes in an environment to minimize loss from a future disaster
- 13. Formed by collapse into the underlying magma chamber
- 14. Firefighters that parachute in to fight wildland fires
- 16. A prolonged dry-climatic event in a particular region that dramatically lowers the available water below that normally used
- 18. The region of the central United States, between Texas and Nebraska that is most noted for frequent tornadoes
- 20. A thundercloud with a flat anvilshaped top; a sign of a thunderstorm
- 22. The amount of burnable material, such as trees and dry vegetation, available for a wildfire
- 24. An acidic volcanic smog produced when volcanic gases react with moisture and oxygen in the air, and sun, to produce aerosols
- 28. The resistance to flow of a fluid because of internal friction
- 31. Process where there is a change in volume and temperature, for example in the atmosphere, without change in total heat content
