The green house effect is first derived from the experience of farmers who live in temperate regions that use greenhouses to grow vegetables and flowers are also of interest. Why do farmers grow vegetables in the greenhouse? Because in the greenhouse temperature is higher than outside the greenhouse. The temperature inside the greenhouse can be higher than outside, because the sunlight penetrates the glass will be reflected back by objects in the room as the greenhouse heat wave in the form of infrared rays, but heat waves are trapped in the room and the greenhouse does not mix with the cold air outside the greenhouse room. That simple description of the greenhouse effect or shortened by ERL.
then from the experience of farmers in the above linked to what happens to the earth and atmosphere. Atmospheric layer that consists of, in succession: the troposphere, stratosphere, and thermosphere mesosfir: The bottom layer (troposphere) is the most important in the case of the greenhouse effect or ERK. About 35% of solar radiation does not reach the earth’s surface. Almost all short-wave radiation (alpha rays, beta and ultraviolet) is absorbed by the top three layers. The others scattered and reflected back into space by gas molecules, clouds and particles. The remaining 65% into the troposphere. In the troposphere, 14% is absorbed by water vapor, dust, and certain gases so that only about 51% that reach the earth’s surface. Of this 51%, 37% is 14% direct radiation and diffuse radiation that has undergone scattering in a layer of the troposphere by gas molecules and dust particles. Radiation received by Earth, some is absorbed partially reflected. Re-emitted radiation is absorbed in the form of infrared rays.
The reflected infrared light is then absorbed by the earth which, among other gas molecules in the form of water vapor or H20, CO2, methane (CH4) and ozone (O3). Infrared heat rays are trapped in layers of the troposphere and therefore the air temperature in the troposphere and the surface of the earth into a rose. Tempers Greenhouse Effect. Gases that absorb infrared rays are called Greenhouse Gases abbreviated as GHG.
If no-ERK, Earth’s average temperature would be around minus 180 degrees C – too cold for human life. With the ERK, Earth’s average temperature 330 degrees C higher at 150 degrees C. so with the greenhouse effect makes the earth’s temperature feasible for human life.
However, when the infrared light beam re-trapped by CO2 and other gases, the infrared rays will bounce back to Earth and Earth’s temperature to rise. Compared with in the 50’s for example, the current global temperature has risen about 0.20 degrees C more.
This can occur because of changes in the composition of GHG (greenhouse gas), which is globally increasing greenhouse gas concentrations due to human activities, especially associated with the burning of fossil fuels (oil, gas, and coal) as in power generation, motor vehicles, air conditioners, computers, cooking. In addition it is also produced from the combustion gases and deforestation as well as agriculture and animal husbandry activities, GHG generated from these activities, such as carbon dioxide, methane, and nitrous oxide. above it is also one of the causes of global warming is happening right now.
picture below is an example of the greenhouse effect that has changed the composition of its greenhouse gases,
