Atmospheric Composition:
●Nitrogen 78.8%
●Oxygen 29.9%
●Argon 0.93%
●Other Permanent Gases; Neon 0.0018%, Helium 0.0005%, Hydrogen 0.00006%, Xenon
0.000009%
●Variable Gases; Water Vapor 0-4%, Carbon Dioxide 0.036%, Methane 0.00017%,
Nitrous Oxide 0.00003%, Ozone 0.000004%, Chlorofluorocarbons 0.00000002%
Temperature = a measure of heat energy
Atmospheric Pressure = the weight per unit area produced by a column of air
Relative Humidity = the ratio of water vapor a given volume of air contains to the maximum
amount it could contain at a given temperature
-Warm air can hold more water vapor than cold
Dew Point = the temperature at which the air becomes saturated
Seasons:
●We have season because of the way the Earth tilts throughout the year
March Equinox = Equator faces sun directly, neither pole tilts towards the sun.
December Solstice = NOrthern Hemisphere tilts away from the sun.
September Equinox = Equator faces sun directly
June Solstice = Northern Hemisphere tilts towards the sun

Document Summary
Other permanent gases; neon 0. 0018%, helium 0. 0005%, hydrogen 0. 00006%, xenon. Variable gases; water vapor 0-4%, carbon dioxide 0. 036%, methane 0. 00017%, Atmospheric pressure = the weight per unit area produced by a column of air. Relative humidity = the ratio of water vapor a given volume of air contains to the maximum amount it could contain at a given temperature. Warm air can hold more water vapor than cold. Dew point = the temperature at which the air becomes saturated. We have season because of the way the earth tilts throughout the year. March equinox = equator faces sun directly, neither pole tilts towards the sun. December solstice = northern hemisphere tilts away from the sun. June solstice = northern hemisphere tilts towards the sun. Convection cells plus the coriolis force produce dominant wind patterns. Latent heat = heat released or absorbed by a substance as it changes state. Evaporation = liquid water absorbs heat and cools the surrounding atmosphere.
