Sample Answer: 
The diagram illustrates the way in which greenhouse gases are produced and further how these gases trap heat from the sun.

One of the most common way gases are released into the earth’s atmosphere is by means of transport. The engine of a car, plane, motorised boat or other vehicles release toxic substances. The pollutants also meet with extra carbon dioxide, evacuated from power plants or factories which burn fossil fuels, forming a clutter of man-made pollutants. The process is fastened also by the marring deforestation, which logs trees that could have absorbed the man-produced carbon dioxide.

The second stage takes place in the atmosphere, where a part of the energy received from the sun should be reflected back to the outer space. Instead, the greenhouse gases trap the heat, warming up the environment.

Overall, it is easy to notice that pollution itself is a complex process, with roots in the mankind actions.

The given diagram illustrates the process how the green house gases entrap the heat from the sun and effects of deforestation on atmosphere.

Firstly the heat from the sun that comes to earth should have been released to the space in an ideal situation. But in reality some amount of heat from the sun radiates in the space and some heat is trapped by the green house gases. In turns that leads to global warming for atmosphere.

In addition to this, carbon dioxide from the man-made sources like trucks, cars and the harmful gases from the factories get mixed with the atmosphere. On the other hand, the trees which absorbed the carbon dioxide are being cut for human needs and that ultimately leads to more catastrophes to the environment.

Thus the human actions and man-made devices are the main reason for green house gases which traps the heats omitted by the sun.
