Occurrence Mechanism Greenhouse



The process of the greenhouse effect is related to the cycle of the sun's heat flow. Approximately 30% of solar radiation reaching the ground is reflected back into space and absorbed by the vapor, carbon dioxide gas, nitrogen, oxygen and other gases in the atmosphere. The remaining 70% is absorbed by the land, sea, and clouds. At night soil and water bodies that are relatively warmer than the air above it. Radiated energy is absorbed back into the atmosphere as infrared radiation, longwave radiation or heat energy. Most of this infrared radiation will be captured by carbon dioxide and water vapor in the atmosphere. Only a small fraction will escape into space. The overall result is that the Earth's surface warmed by the presence of molecules of water vapor, carbon dioxide, and the like. This heating effect is known as the greenhouse effect.
While the process in a nutshell that is when the sun's rays penetrate the glass as the radiation of short wave so that the heat of the earth and diserapa by existing plants in the greenhouse. Henceforth, the heat is on radiasikan back, but with long wavelengths (long compared to the energy geklombang) so that the radiation beam can not penetrate glass. As a result, the temperature inside the greenhouse is higher than the temperature outside the greenhouse.
