1 DO NOW: COPY THIS IN COMP BOOK Objectives:Describe the Earth’s atmosphere.Identify three methods of heat transfer.Explain the greenhouse effect.Key Terms:OzoneRadiationConductionConvectionGreenhouse Effect
22 Heating of the Atmosphere Solar energy reaches Earth as electromagnetic radiation
23 Heating of the Atmosphere Oceans and land radiate absorbed energy back into the atmosphere.Dark objects absorb more solar radiation than light objects.
24 Greenhouse EffectSunlight penetrates atmosphere (warms surface of Earth).Greenhouse gases (CO2, methane, and nitrous oxide) and water vapor absorb some radiation (rest is lost to space).Causes warming of the surface and lower atmosphere of EarthNecessary for life to exist.
