Greenhouse Glass, the material that greenhouse is made of, 1) transmit short -wavelength visible light, 2) absorbs and redirects the longer wavelengths of energy. These two aspects make the greenhouse warmer than outside air temperature

Greenhouse effect of the atmosphere • Light from the sun includes the entire visible region and smaller portions of the adjacent UV and infrared regions. • Sunlight penetrates the atmosphere and warms the earth’s surface. • Longer wavelength infrared radiation is radiated from the earth’s surface. • A considerable amount of the outgoing IR radiation is absorbed by gases in the atmosphere and reradiated back to earth. The gases in the atmosphere that act like glass in a greenhouse are called greenhouse gases
Natural greenhouse effect ATMOSPHERE Infrared Radiation Solar Radiation The natural greenhouse effect causes the mean temperature of the earth's surface to be about 3 3oc warmer than it would be if natural greenhouse gases were not present
Natural Greenhouse effect The natural greenhouse effect causes the mean temperature of the Earth's surface to be about 33oC warmer than it would be if natural greenhouse gases were not present
