The Sun provides energy in the form of heat to a planet, say for example Earth. This radiation energy is not all absorbed by the planet but only half of the total energy is directly absorbed by the surface. The other half is reflected back into the space due to clouds and the atmosphere of the planet. A lot of radiation is also reflected from the surface of the earth which goes back into the atmosphere.
What the atmosphere does is reflects radiation in all directions and some of that radiation comes back into the earth’s surface and that process is called greenhouse effect. It is nothing but a process involving earth’s atmosphere transferring some of the heat energy in the form of radiation back into the surface to keep Earth warm. This is a very important process in making Earth suitable for living things because without this atmosphere helping the planet, there would be no life form on our planet.
The above diagram clearly tells you all everything. You can see the Sun which is sending it’s energy to the planet Earth. How some of that energy is being diverted upwards and some of it passes through to the surface. The energy that manages to come to the planet is also getting reflected back towards the atmosphere and some of that energy is what atmosphere throws back into the surface and this cycles goes on and on.
If you are wondering that this has anything to do with the greenhouse associated to plants you read in your Science subject at school then you are mistaken. That greenhouse effect was about building a glass building with plants inside it. That building used to trap all the heat and not let it escape as you know glasses trap heat from outside to inside and not let it reflect outside. This process helps in keeping the plants warmer and help it grow faster and stronger. The greenhouse effect we are talking about today has nothing to do with this process and is more to do with the earth’s natural greenhouse effect with the help of it’s atmosphere.
Did you know that even Mars and Venus has this greenhouse effect? In fact Venus has such a thick atmosphere that it has an even stronger heat radiation making it relatively a warmer planet due to this process. Mars on the other hand has a thin atmosphere and thus the effect of this process is really less. Only Earth is good enough and perfectly built to keep it warm and cool enough to make life form possible, thanks to gods.
Let me show an interesting video to you that will clear a lot of your doubts:
I am sure you have got a good idea about green house warming by now as we begin our journey with an introductory article. We are going to cover several important topics including global warming in our blog. What we intend to do with this website is to educate you people of all the things that are happening in our world and is related to green house gases and global warming. What are the things responsible for protecting and destroying our country we shall discuss in our site. Stay tuned folks!
