Transcript

  • 1. -DEVESH JALAN
  • 2.  The burning of fossil fuels releases various gases such as sulphur dioxide , carbon monoxide , carbon dioxide into the atmosphere which leads to global warming, pollution of the air ,water and land.
  • 3.  Some harmful effects are – ◦ Global warming ◦ Greenhouse effect ◦ Deathly diseases
  • 4.  Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation  It is caused by greenhouse effect
  • 5.  The greenhouse effect is the process by which absorption and emission of infrared ra diation by gases in the atmosphere warm a planet's lower atmosphere and surface.
  • 6.  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 and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases
  • 7. A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the Solar System, the atmospheres of Venus, Mars, and Titan also contain gases that cause greenhouse effects
  • 8.  Some diseases caused by excessive use of fossil fuels are- ◦ Cancer  Lungs  Brain  Blood ◦ Asthama ◦ Memory loss
