Atmosphere

2. trapping of the suns warmth in a planets lower atmosphere
4. middle layer, coldest layer, protects earth from meteoroids, meteoroids usually burn up in the layer
7. harmful to ozone, owing to the release of chlorine atoms on exposure to ultraviolet radiation
8. weather conditions prevailing in an area in general over a long period of time
10. envelope of gases surrounding the earth of another planet
15. presence of introduction into the environment of substance that has harmful or poisoness' effects
17. production/discharge of something, gas or radiation
18. height of an object or point in relation to sea/ground level
20. reversal of the normal behavior of temperature in the troposphere
22. gradual increase in overall temperature, attributed to greenhouse effect
26. region above troposphere, ozone layer
27. natural fuel such as coal or gas, formally passed living organisms

1. narrow variable band of very strong air currents encircling the globe several miles up the earth
3. hottest layer with more than 2000 degrees fahrenheit, space begins here, ISS located here
5. large rotating storm with high-speed winds that form over warm waters in the tropical areas
6. absorbs most of the ultraviolet radiation reaching earth from sun, UV-A gets through the zone, UV-B cannot
9. furthest layer from earth, extends into the outer space
11. climate pattern that describes the unusual warming of surface waters
12. phenomenon that describes cooler than normal ocean surface temperatures
13. amount of water vapor in the air
14. state of atmosphere at a place and time in a short time period
16. rising of sea water, magma, or other liquids
19. mobile destructive vortex rotating winds have the appearance of a funnel-shaped cloud
21. lowest region of the atmosphere layer closest to the earth
23. degree to which the ambient air is pollution free, assessed by measuring a number of indicators of pollution
24. emission of energy as electromagnetic waves or as moving subatomic particles
25. movement back and forth at regular speed
