Greenhouse effect presentaion Greece

  1. 1. The Earth receives a total solar radiation, corresponding to a flow of about1966 W/m2, the boundary of the atmosphere. One part of this is absorbed by the systemearth-atmosphere, the remainder escapes into space. Approximately 30% of the incoming solar radiation is reflected, in 6% of theatmosphere, 3% from the clouds and 4% of the Earths surface. About 70% of solar radiation absorbed by 32% from the atmosphere (including the stratospheric ozone layer) by 3% from the clouds and the large majority (51%) of the surface and the oceans.
  2. 2. The presentation and understanding of the greenhouse effectThe presentation of the phenomenon with picturesThe chronological presentation of the history of the phenomenonHow compounded phenomenon and what causes it, what the results ofWhat are the greenhouse gasesHow can we reduce greenhouse gases how can we, our school and our home to help reduce greenhouse gases
  3. 3. All gaseous components of the atmosphere thatcontribute to the greenhouse effect, collectivelyreferred to with the term greenhouse gases.Absorb longwave terrestrial radiation and re-emit thermal radiation heating the surface.Certain gases such as ozone, have translucencyand solar radiation, thus absorbing a partof, contributing to a degree and cooling of theearths surface.
  4. 4. The greenhouse effect is natural, but enhanced by human activity, which contributes to increased concentration of greenhouse gases and the release of other trace elements, such as chlorofluorocarbons (CFCs). In recent years, recorded an increase in the concentration of several greenhouse gases, and particularly in the case of carbon dioxide, the increase was 31% in the period 1750-1998. Three-quarters of the anthropogenic production of carbon dioxide due to fossil fuel use, while the rest comes from changes on the ground, mainly through deforestation. Besides humans, methane produced by animals (e.g. cows) with the burping
