Materials –Atmospheric dust –Soil and salt –Ash from fires and volcanoes –Particulate matter from combustion, skin, hair, bits of clothing [fibers], pollen, bacteria, viruses, liquid aerosols.
Air Pressure –The atmosphere is pulled to the Earth by gravity –More dense near the surface because of this gravitational pull –Pressure at sea level = 14.5 lbs/sq.in.
Layers of the Atmosphere Troposphere Stratosphere – Ozone layer Mesosphere Thermosphere - Ionosphere Exosphere – transition to space
Atmospheric Temperatures –F = (C x 1.8) + 32 –C = (F – 32) x.55
Energy in the Atmosphere –Radiation –Conduction –Convection
Heating and Movement of Energy Greenhouse Effect Water Vapor Carbon Dioxide Methane Nitrous Oxide Infrared Radiation The Earth’s Atmosphere
