The atmosphere is the layer of gases that surround the earth, and it provides the air that we need to stay alive. Although the majority of the atmosphere is made of nitrogen and oxygen, there are other gases found in trace amounts that are known as greenhouse gases....
What are Greenhouse Gases ?Gillenwater, Michael
Since the Industrial Revolution, humans have been releasing larger quantities of greenhouse gases into the atmosphere. In the past century that amount has increased dramatically, with the knock-on effect of global warming. Global temperatures have accelerated in the past 30 years and are now the hi...
Now, the Earth’s atmosphere does the same as greenhouse do. During the day when the sun shines, it heats up the Earth’s atmosphere. The Earth absorbs some of this energy and heats up. At night, when temperature goes down, the Earth cools down by giving different form of energy calle...
What are the Greenhouse Gases? A greenhouse gas absorbs and emits radiant energy in the thermal infrared region, resulting in the greenhouse effect. Greenhouse gases are essential for maintaining a livable temperature on Earth. The average surface temperature of the Earth would be around 18°C if...
Greenhouse gases are naturally occurring gases, such as CO2, methane, and sulfur dioxide, that trap heat on Earth—like a greenhouse traps heat to grow tomatoes in cold climates. According to NASA, without greenhouse gases, the average temperature on Earth would be 0°F (–18°C), rather ...
The greenhouse effect is entirely due to the fact that the atmosphere absorbs and emits infrared energy, combined with a heat source to warm the bottom of the atmosphere (in our case, the Sun) and the cold depths of outer space above the top of the atmosphere. The greenhouse gases (and ...

Here we shall learn what the greenhouse gases are, how it is emitted by human activity and also how to reduce such emissions.They are Carbon dioxide , Methane, Nitrous oxide, Some industrial gases such as hydro fluorocarbons, Per fluorocarbons, Sulphur h
Why are greenhouse gases important? The proliferation of greenhouse gases from many sources threatens to increase the average global temperature. The threat ofglobal warming has long-term consequences, such as rising sea water levels and increasingly severe weather. ...
