- 3. a form of oxygen gas, absorbs ultraviolet rays from the sun and then releases some of this energy in the form of heat.
- 7. the length of time substance remains in suspension within a system
- 9. high-speed particles, mostly protons and electrons, traveling rapidly outward from the Sun.
- 10. a shell of gas around the earth with multiple layers
- 12. a colorless, odorless, and highly flammable gas, and the main component in natural gas
- 16. ozone that is in the stratosphere, between about 6 and 30 miles above Earth’s surface
- 17. the circulation and re-utilization of carbon atoms especially via the process of photosynthesis and respiration.
- 18. height above sea level or the earth's surface
- 19. CFC’s
- 20. a type of invisible radiation that is released by the sun
- 22. the average conditions of temperature, precipitation, winds, and clouds in an area
- 23. upper most layer of Earth's atmosphere; has two layers ionosphere and exosphere
- 24. the most abundant gas in the atmosphere
Down
- 1. trap heat in the atmosphere
- 2. the transfer of heat thru the movement of a fluid, either a gas or liquid
- 4. the measure of the force with which air molecules push
- 5. the phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.
- 6. the abundance or volume of gas which is present within earth’s atmosphere
- 8. makes up the majority of greenhouse gases
- 11. an instrument used to measure air pressure
- 12. the layer of the atmosphere between the stratosphere and thermosphere in which temp decreases as altitude increases
- 13. the main theory explaining the formation of the first atmosphere
- 14. an increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change.
- 15. the layer of the atmosphere that is above the troposphere and in which temperature increases as altitude increases
- 21. the second most abundant gas in the atmosphere
- 23. the lowest layer of the atmosphere, in which temperature decreases at a constant rate as altitude increases
