Greenhouse gases or GHG or GhG, are the gases that under the thermal infrared range, absorb and emit radiant energy causing the greenhouse effect. The greenhouse gases consist of various gases which include Carbon dioxide, methane, water vapor, and ozone. The greenhouse gases maintain the temperature of the earth which is 15°C, if the greenhouse gases are not present on earth, the temperature of the earth will be -18°C. Not only earth, but planets like Venus, and Mars also have greenhouse gases.
Today, carbon dioxide is increased up to 50% in the atmosphere due to human activities. The industrial revolution in the world has caused an increase in carbon dioxide from 280 ppm to 419 at present. A massive amount of carbon dioxide is produced due to the combustion of fossil fuels like coal, petroleum, and natural gas, manufacturing of cement, fertilizer, and deforestation.

The main constituents of Earth’s atmosphere such as Nitrogen, oxygen, and Argon are not a part of greenhouse gases. These molecules contain two atoms of the same elements like N2 and O2, which do not let the electrical charge distribute when these molecules vibrate and argon is a monatomic gas that doesn’t vibrate. These gases are not affected by infrared radiation and hence, these are not greenhouse gases. If we consider some molecules which have two atoms of different elements and absorb infrared radiation like Carbon monoxide and hydrogen chloride, these molecules are short-lived in the atmosphere, hence, these gases are also not considered greenhouse gases.
Greenhouse gases are those that absorb and emit infrared radiation. The accepted greenhouse gases are carbon dioxide, nitrogen oxide, methane, and ozone. The most abundantly found greenhouse gases in the atmosphere are as follows.
1. What is the greenhouse effect?
Ans. The energy coming from the sun is trapped, reflected, or transmitted by the earth’s atmosphere. Greenhouse gases trap these energies, which means these gages absorb infrared radiation and increase the temperature. This results in the greenhouse effect.
2. Name any two greenhouse gases?
Ans. Methane and carbon dioxide are two components of greenhouse gases.
3. Which greenhouse gases produce the maximum Greenhouse effect?
Ans. Water Vapour contributes to the maximum production of the greenhouse effect.
4. Is ozone a greenhouse gas?
Ans. Ozone is a component of greenhouse gas.
