Across
- 2. An air mass responsible for cold, moist air
- 7. A destructive, rotating column of air that has very high wind speeds and that may be visible as a funnel-shaped cloud
- 8. The movement of matter due to differences in density caused by temperature variation
- 9. The curving of the path of a moving object from an otherwise straight path due to earth’s rotation
- 12. Highest altitude, feathery clouds composed of ice crystals
- 13. Study of the alignment of magnetic minerals in rock
- 15. Magma that flows onto earth’s surface; the rock that forms when lava cools and solidifies
- 17. All forms of energy that travel through space as waves
- 18. A seismic wave that travels through the body of a medium
- 19. A usually brief, heavy storm that consists of rain, strong winds, lightning, and thunder
- 20. An instrument that records ground vibrations
- 22. A fossil used to date rock layers
- 24. The lowest layer of the atmosphere, in which temperature drops as altitude increases and in which weather conditions exist
Down
- 1. A layer of sediment deposited annually
- 3. Type of rock that forms when magma cools and hardens
- 4. The sudden return of elastically deformed rock to its undeformed shape
- 5. Formation of a large droplet by the combination of smaller droplets
- 6. Layer of plastic rock just below the lithosphere
- 10. The actual amount of water vapor contained in a given volume of air
- 11. Cooling a below its freezing point, condensation point, or sublimation point without a change in state
- 14. A volcanically active area of earth’s surface, commonly far from a tectonic plate boundary
- 16. The fastest seismic wave; can travel through solids, liquids, and gases
- 21. Temperature at which the rate of condensation is the same as the rate of evaporation
- 23. Any activity that includes the movement of magma toward or onto earth’s surface
- 25. A system that uses reflected radio waves to determine the velocity and location of objects
