Document Summary
July and august avg. temperatures over (0 degrees) In toronto only 21/2 months are below freezing (0 degrees) the rest over. Electromagnetic (em) radiation: em varies with frequency/wavelength making different properties of energy - the em spectrum, absorption. Atmosphere structure: atmosphere absorbs heat energy and then it spreads around the globe, as we increase the levels of energy in our atmosphere we alter the, radiation environment, density (pressure, temperature. Absorption of terrestrial radiation: water vapor: an excellent absorber of terrestrial radiation in wavelengths less than. 7um: carbon dioxide: an excellent absorber of terrestrial radiation in wavelengths longer than 12 um, methane: an excellent absorber of terrestrial radiation in wavelengths near 7 um. Composition of atmosphere: human activities have altered the composition of since the pre-industrial era. Earths greenhouse effect: solar radiation fluctuates but its not coinciding with the heat that"s trapped within the atmosphere, energy is neither created or destroyed it is stored, stored open water (earths oceans/seas)
