Across
- 3. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
- 4. an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect
- 7. the region of the upper atmosphere in which temperature increases continuously with altitude,
- 8. the process in which energy is emitted as particles or waves.the complete process in which energy is emitte
- 12. the lowest layer of the atmosphere, 6 miles (10 km) high in some areas and as much as 12 miles
- 13. the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure
- 15. the natural sequence through which water passes into the atmosphere as water vapor, precipitates to earth in liquid or solid form, and ultimately returns to the atmosphere through evaporation.
Down
- 1. the envelope of gases surrounding the earth or another planet.
- 2. the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts
- 5. the force exerted by air, whether compressed or unconfined, on any surface in contact with it
- 6. an effect occurring in greenhouses in which radiant heat from the sun passes through the glass warming the contents, the radiant heat from inside being trapped
- 9. the region of the upper atmosphere extending upward from the tropopause to about 30 miles
- 10. a form of oxygen, O 3, with a peculiar odor suggesting that of weak chlorine, produced when an electric spark or ultraviolet light is passed through air or oxygen
- 11. the region between the ionosphere and the exosphere, extending from about 250-650 miles
- 14. the height of anything above a given planetary reference plane, especially above sea level on earth.
