                                              GREENHOUSE EFFECT


Greenhouse effect is the phenomenon whereby certain gases, which are components of a planetary atmosphere, they retain some of the energy emitted by the soil have been heated by solar radiation. It affects all planetary bodies endowed with atmosphere. According to the majority of the scientific community, the greenhouse effect is being increased in the earth by the emission of certain gases such as carbon dioxide and methane due to human activity.



But the main gas that causes over which is the greenhouse effect is carbon dioxide because this gas is the most we have in the atmosphere.



Currently, CO2 in the atmosphere is growing so unnatural by human activities, mainly by burning coal, oil and natural gas that is releasing the carbon stored in these fuels and deforestation of the trees.



Trees are very important for our environment because they help us to turn what is the carbon dioxide to fresh air if we finish with the trees soon VAMS have oxygen instead we will have only what is dioxide carbon.



This effect is one of the main factors that cause the greenhouse effect on the planet because this effect causes it to accumulate a lot of gas, such as:



CO2

H2o

o3

CH4



These are the main gases that make up what is the greenhouse effect
