composition of atomosphere correct answers 78% N2, 21 % O2, trace gases fixed trace gases of the atmosphere correct answers argon, carbon dioxide, neon, helium, hydrogen, and xenon variable trace gases of the atmosphere correct answers water vapour, pollutants troposphere correct answers 0-17 km above Earth's surface, site of weather, organisms, contains most atmospheric water vapor. (temperature decreases with increasing altitude, pressure decreases) stratosphere correct answers 2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature increases with altitude increase. mesosphere correct answers A layer of the atmosphere fifty to eighty kilometers above the Earth's surface thermosphere correct answers The uppermost layer of the atmosphere, in which temperature increases as altitude increases electromagnetic spectrum correct answers Includes all forms of electromagnetic radiation, with the only differences in the types of radiation being their frequencies and wavelengths e.g various wavelengths emitted by the sun. absorption and the energy correct answers about 70% of radiation absorbed by atmosphere and land. contributes to heating and photosynthesis reflection and the energy correct answers about 30% radiation is reflected by atmosphere and land. The energy bounces off the surface is is redirected back out to space. albedo correct answers Ability of a surface to reflect light. (e.g cryosphere) water vapour correct answers largest contributing natural occurring greenhouse gas. Responsible for 65% of the warming influence. Carbon Dioxide correct answers second largest contributing natural occurring greenhouse gas. Responsible for 25% of the warming influence. cultural greenhouse effect correct answers arises from the emission of additional quantities of greenhouse gases as well as production of new greenhouse gases as well, more outgoing IR is absorbed and contributes to the overall warming of the lower atmosphere
