Document Summary
Air pollution essentials: the atmosphere contains many gases. 40 trace gases: ozone, helium, hydrogen, nitrogen oxides. Troposphere: troposphere: 5-10 miles thick, where our weather happens, gets colder as you go higher in altitude, well-mixed, pollutants well-mixed, capped by tropopause. Stratosphere: temperature increases with altitude, up to 40 miles above earth, contains ozone (what"s ozone?, o3 absorbs high-energy radiation from sun, little mixing, capped by stratopause. Altitudes: the cruising altitude of a typical 747 jet is 35,000 feet (or 12,000 meters), the concorde jet cruises at 18,300 meters. Precipitation: climate: the result of long-term weather patterns for a particular region. A function of its rainfall and temperature: meteorology: the study of both weather and climate. A biome is a large area of the earth"s surface with similar plants and climate. Solar energy: solar energy comes from the sun and it reaches the earth, this solar energy includes:
