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
