A representation of the exchanges of energy between the source (the Sun), the Earth's surface, the Earth's atmosphere, and the ultimate sink outer space. The ability of the atmosphere to capture and recycle energy emitted by the Earth surface is the defining characteristic of the greenhouse effect.The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface, energy is transferred to the surface and the lower atmosphere. As a result, the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism.Solar radiation at the high frequencies of visible light passes through the atmosphere to warm the planetary surface, which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.
Under debris means all man-made objects and their fragments in space, which is already defective, do not function and never will be able to serve any useful purpose, but it is a dangerous factor affecting the operating spacecraft (SC), especially manned. In some cases, large or containing dangerous on board (nuclear, toxic, and so on. N.) Material debris objects can pose a direct danger to the Earth - in their uncontrolled descent from orbit, the incomplete combustion of the passage of the dense layers of the Earth's atmosphere and loss of fragments on settlements, industrial sites, transportation routes, and so on. n
