The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The most abundant gas in the atmosphere is nitrogen, with oxygen second.
1 The earth's atmosphere contains trace gases, some of which absorb heat. 2  These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases.. 3  Albedo has an important influence on the earth's temperature.4  Greenhouses are structures designed to retain heat. The earth's greenhouse effect is what makes this planet suitable for life as we know it. 2  The earth's atmosphere contains trace gases, some of which absorb heat. 3  These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases..
