Greenhouse Effect
Earth’s atmospheric greenhouse effect associated with radiation processes going on inside. radiation is a form of energy, and is transmitted only in a vacuum.
Other forms of energy transmission in the natural environment are conduction and convection. In conduction heat spreads through the solid (propagation of heat from the surface soil to a lower level). In a fluid (gas and liquid) heat transfer by convection process through which a relatively warm part of the fluid, moving, and then mixed and integrated into a relatively cool environment.
Characteristics of the radiation, which spread in the form of electromagnetic waves associated with a body temperature that issues it. In the present atmosphere of two types of radiation. On one side is the solar radiation coming from the surface of the sun around 6000 ยบ C. This is mainly manifested in the form of visible light rays.
In addition, like the Sun, Earth’s surface (continents, oceans, polar caps) and the atmosphere also emit radiation, but with energy levels much lower than the del Sol is called infrared radiation is not visible, but spread in a similar way to sunlight. The atmosphere is transparent to solar radiation is far more opaque to infrared radiation originating from Earth’s surface.
