  8. Solar Radiation • 70% of the suns solar radiation is absorbed by Earth’s land, ocean, & atmosphere. • 30% of the suns solar radiation is reflected by clouds, dust, air & land.

  9. Greenhouse gases radiate energy back to Earth’s surface. Some radiation escapes back into space. NO2 CO2 CH4 H2O 100% of the solar radiation. Gases in the troposhere.

  10. The warming of the Earth’s surface and troposphere from gases that trap heat. • The burning of fossil fuels adds CO2 • Deforestation (removing trees) reduces the use of CO2 by decreasing photosynthesis. • The warmer the Earth, the more gases it traps. Greenhouse effect

  11. Greenhouse effect • Major gases: • (H2O) Water • (CO2) Carbon dioxide(from burning fossil fuels) • (CH4) Methane(fossil fuels, livestock, landfills) • (NO2) Nitrous oxide(fossil fuels, fertilizers) • (O3) Ozone • (CCl3F) CFCs (chlorofluorocarbon)

  12. Satellites meteor O3 O3 Ozone layer O3 O3 O3 O3 CO2 CO2 H2O H2O

  13. Exosphere – “outer space” • Thermosphere – satellites are placed • Mesosphere – meteors burn up • Stratosphere – ozone layer, airplanes fly • Troposhere– all weather occurs, almost all H2O and CO2 in the atmosphere Layers of the Atmosphere

  14. Ozone layer • Ozone is O3 • Absorbs harmful ultraviolet radiation from the sun. (Earth’s sunscreen!) • Has been damaged by humans use of CFCs (chlorofluorocarbon) CCl3F and exhaust compounds (from airplanes). • CCl3F CCl2F + Cl UV radiation • Naturally the ozone layer thins “the hole” in the Spring over the Antarctic.

  16. Normal Conditions: Warm air near the Earth rises.(Air is heated from below as the sun warms the Earth’s surface.)

  17. Inversion Conditions: Colder air is near the Earth, trapped under warm air.Caused when a warm front (air mass) moves over a cold front (air mass). Solar Radiation
