yes .. then you come down to earth after accomplishing danmerkurferðina and taken the real deal. But in the natural sciences bioethanol in the first week was lecturing time on Monday and Thursday time was again lecture and started also in poster bioethanol work we finished then the time on Friday.
Thermal Radiation from the sun warms the earth, but not all controls surface temperature. Earth also radiates from the heat, just like the sun. We see well the radiation from the sun, because most of it is visible light. Thermal bioethanol radiation from the earth the other hand, far beyond the visible range.
Physicists have long known that the concentration of thermal radiation increases with temperature. They will promise the earth, the more it radiates from him. Earth can not radiate a more heat than it receives from the sun so that the balance is achieved at temperatures where overall radiance of the earth is equal to the thermal radiation that comes from the sun.
Although the concentration of thermal radiation grow with temperature bioethanol he is also dependent on other factors. These factors reduce the level of radiation is obtained at a given temperature. In the Earth's atmosphere are certain gases have just such an effect. Their presence means that at a given temperature radiant atmosphere less than he would do if these gases were not present. In the total radiation of the earth may equal the heat obtained from the sun heating the ground needs to be higher than otherwise. These gases are called bioethanol greenhouse gases and their impact on the greenhouse effect.
But how these gases raise the surface temperature of the earth? When describing billion out of the darkness reflected light from the road and other things that it falls on. We would be surprised if the air swallowed bioethanol simply light. It does not happen because the Earth's atmosphere is relatively transparent visible light.
Thermal radiation of the earth is not visible light, but infrared light. Greenhouse gases in the atmosphere are not transparent infrared light. They absorb varmageislunina from Earth and beam then part of her remains into space, but also endurgeislast part of it down to the surface. This re-radiation from the atmosphere down to the surface heats yfirborðiðið, that radiates more heat.
Greenhouse bioethanol gases absorb also the increased thermal radiation, is part of such re-radiated to the ground heats the surface bioethanol further. The amount of greenhouse gases in the atmosphere determines any heat balance is achieved. On Earth steady state when the greenhouse effect have raised the temperature of 33 C
