Air Pollution What Is Air Pollution??                     Air pollution is the introduction of  chemiclas, particular matter, or biological materials that cause harm to discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. Types Of Air Pollution There are several types of air pollution, mainly Indoor Air Pollution and Outdoor Air Pollution. These include smog, acid rain, the green house effect and hole in ozone layer. One type of air pollution is the release of particles into the air. Another type of air pollution is the release of poisonous gases.  Outdoor Air Pollution Smog Smog is a type of large scale out pollution. It is caused by chemical reaction between pollutants derived from different sources. Indoor Air Pollution      It more dangerous than outdoor air pollution because we do everything in enclosed environment where air circulation may be restricted. Sources of Indoor Air Pollution Tobacco

Global Warming ppt

  GLOBAL WARMING   Introduction Global Warming is the increase in average temperature of the earths near surface air and oceans. Most of the observed temperature increase is caused by increase concentration of greenhouse gases.  Major gases                             water vapour     = 36-70%           carbon dioxide  = 9-26%           methane           = 4-9%           ozone               = 3-7% Causes of global warming Emission of green house gas like carbon dioxide, methane, nitrous oxide etc. The major source is carbon dioxide (80%). 20% by methane and nitrous oxide . Carbon dioxide The major source of carbon dioxide is the power plants. Burning of fossil fuels for the purpose of electricity generation . About 20% of carbon dioxide emitted in the atmosphere comes from burning of gasoline in engines of the vehicles.  Methane Methane is more than 20 times as effectual as carbon dioxide at entrapping heat in the atmosphere. Methane is obtained from resources such as rice padd
