10. Hydrosphere 20. Chlorofluorocarbons

1.  NH3 (Ammonia)- Volcanoes and lava covered earth which gave of this gas which was part of earth’s first atmosphere

2.  Atmosphere- Gas portion of the earth, envelope of gas surrounding Earth.

3.  CH4 (METHANE)- Volcanoes and lava covered earth which gave of this gas which was part of earth’s first atmosphere

4.  Troposphere-lowest layer of atmosphere, most dense, weather occurs here

5.  N2 (NITROGEN)-most abundant gas in our present atmosphere (78%)

6.  Stratosphere-second layer of the atmosphere, contains the ozone layer

7.  H2 (HYDROGEN)- pushed to the outer parts of our solar system by the solar wind after it escapes earth’s gravitational pull

8.  Mesosphere-3rd/middle layer of the atmosphere, coldest temps. and meteors burn up

9.  CO2 (CARBON DIOXIDE)- Bacteria use CO2 and sun light to make food. As a waste product O2 is given off and enters the early atmosphere

10.  Thermosphere-4th layer of the atmosphere that contains the ionosphere, satellites orbit here

11.  O2 (OXYGEN)-second most abundant gas in our present atmosphere (21%)

12.  Ionosphere- area inside the thermosphere where, from the suns rays, change gases into ions

13.  H2O vapor-varies percentage from place to place

14.  Exosphere-outermost layer of the atmosphere, shuttle missions will orbit here

15.  Trace Elements- the smallest portion of our atmosphere 1-4 %. Many Gases.

16.  Ozone-contains 3 oxygen atoms, absorbs most of the ultra violet radiation that enters the earth

17.  Lithosphere-solid/rocky portion of the earth, means stone sphere

18.  Ultra Violet Radiation-wavelength of electromagnetic radiation from the Sun, some filtered out by ozone (UVc)

19.  Hydrosphere-water portion of Earth (ground water, surface water, and clouds)

20.  Chlorofluorocarbons- CFC’s are made up of 3 Chlorine atoms, 1 Fluorine atom, and 1 Carbon atom. CFC’s are found in refrigerating systems, aerosol cans, and Styrofoam packaging and contribute to the destruction of ozone.
