1. Understanding the Greenhouse Effect The Impact of the Greenhouse gases on the Earth

2. The Greenhouse Gases  Water Vapor – most powerful ( due to water’s large heat capacity and creates clouds)  Carbon Dioxide (Naturally occurs and caused burning of Fossil Fuels)  Methane (Natural and Human Made)  CFC’s (Human Only)  Ozone (Natural and Human Pollution)  Nitrous Oxide (Natural 60% and Human Pollution 40%)

3. The Greenhouse Cycle

4. The 5 Steps  Sunlight reaches Earth  Sunlight energy absorbed by Earth’s Surface; transformed into heat and Radiated out  Radiation warms Air  Radiation blocked by Greenhouse gases and Clouds and return heat to Earth’s surface  Some Radiation exits into Space.
