Model Answer 1:
The given diagram explains how sun emitted energy gets trapped in our atmosphere due to the greenhouse effect. It is evident that logging of trees and fossil fuel driven vehicles worsen the greenhouse effect.

Getting back to the details, sunlight that reaches the earth surface creates heats and a large portion of this heat was supposed to radiate back to the Space without any hindrance. However, this is not the case and a great proportion of heat energy remains on earth due to different greenhouse gases. Though some sunlight is reflected off our atmosphere for the presence of the white cloud in the sky, a large portion of the heat created by sunlight rays do not leave the surface. Tree logging is a reason for enhanced greenhouse effect as less tree means less absorption of CO2, which is the main gas of greenhouse problem. Another aspect that enhances the average surface temperature by contributing to greenhouse phenomenon is the fossil fuel. This fuel is used to run different water and Highland vehicles and is responsible for the increasing emission of carbon dioxide gas. It is evident that to reduce the average temperature which is basically generated by the greenhouse effect, we need more trees and less use of fossil fuels to drive our cars and ships.

Sample Answer 2: 
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 how the green house gases entrap the heat from the sun and how deforestation affects our atmosphere.

Getting back to the details, the heat created by sunlight that comes to earth should have been released to 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 on Earth. In turns, this leads to the global warming.

In addition to this, carbon dioxide from the man-made sources like trucks, cars and the harmful gases from the factories mix with the atmosphere. On the other hand, 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.
