Investigate the cause of the greenhouse effect by completing each sentence. greenhouse gases solar radiation infrared carbon dioxide fossil fuels water vapor solar The heat within earth's atmosphere originates from radiation. This energy is trapped near the earth by molecules in the atmosphere called Major greenhouse gases are carbon dioxide, CFCS, methane, ozone, nitrous oxide, and Most of the radiation from the Earth's surface is absorbed by greenhouse gases and reflected back to earth.
