Physical Science
Across
- 1. front/a front along which a cold air mass thrust beneath a warmer air mass.
- 4. the location on the earth’s surface directly above the focus of an earthquake
- 8. a small earthquake often precedes a major earthquake originates
- 12. a frictions of total radiation that is reflected back by a surface
- 13. point
- 14. transfer heat from one object to the next pot on stove
- 15. /the 2890 kilometer thick layer of earth located below the crust
- 17. seasonal reversal of wind direction associated with large continents, especially asia; in winter, the wind blows from sea to land.
- 18. vibration of earth produced by rapid release of energy
- 20. point/ the temperature to which air has to be cooled in order to reach saturation
- 21. / the rigid outer layer of earth including the crust and upper mantle.
- 22. core /a layer beneath the mantle about 2260 kilometers thick; the outer core contains liquid iron and generates earth’s magnetic field
- 23. rebound/ tendency for deformed rock
- 26. an instrument that measures atmospheric pressure
- 27. thermal energy transferred from one object to another
Down
- 2. boundary/ a region where the rigid plates are moving apart
- 3. the point within earth where an earthquake originates
- 5. the process of converting a liquid to a gas
- 6. a low pressure center characterized by a counterclockwise flow of air in northern hemisphere
- 7. the boundary between two adjoining air masses having contrasting characteristics.
- 9. / a molecule of oxygen containing three oxygen atoms
- 10. proposed supercontinent that 200 million years ago began to break apart and from the present landmasses
- 11. core/ the solid innermost layer of earth , about 1220 kilometers in radius.
- 16. heat / the energy absorbed or released during a change of state.
- 17. the layer of the atmosphere immediately above the stratosphere and characterized by decreasing temperatures with height
- 19. wall/ a doughnut- shaped area of intense cumulonimbus development and very strong winds that surrounds the eye of a hurricane.
- 24. /a general term referring to water vapor in the of earth air but not to liquid droplets of fog ,cloud, or rain.
- 25. the thin rocky outer layer of earth.
