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