what s green house effect

The radiation from the sun enter the Earth’s atmosphere but are unable to escape. This increases the temperature of the Earth. This is called the greenhouse effect.

Plants absorb carbon dioxide from the atmosphere to synthesize their own food through the process of photosynthesis.  However, as a result of deforestation, the number of trees has gone down drastically. This has reduced the uptake of carbon dioxide by trees, which in turn has led to an increase in its concentration in the atmosphere. The burning of fossil fuels further adds to the carbon dioxide levels in the atmosphere. As a result, more and more solar radiation is being trapped in the atmosphere, thereby leading to an increase in the Earth’s temperature. This warming-up of the Earth is termed as global warming. Other gases such as methane, nitrous oxide, and water vapor also contribute to the greenhouse effect.

The GREEN HOUSE is a naturally occurring process that aids in heating the Earth's surface and atmosphere. It results from the fact that certain atmospheric gases, such as , CO2 and CH4 are able to change the energy balance of the planet by absorbing  RADIATIONS emitted from the Earth's surface. Without the greenhouse effect life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18° Celsius, rather than the present 15° Celsius.

 The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere(water vapor, carbon dioxidenitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

 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.
