Which of the following pairs of gases is mainly responsible for green house effect?

Question

Consider the following statements about ozone :
(a) Ozone is poisonous gas.
(b)Ozone shields the earth's surface from the infrared radiation from the sun.
(c) Ozone is a product of UV radiations acting on oxygen molecule.
(d) At the lower level of the earth's atmosphere, ozone performs most essential function.
The correct statements are

Answer 1

The question asks which pair of gases is mainly responsible for the greenhouse effect. Let's evaluate the options and understand the science behind each.

Ozone and Ammonia: While ozone does contribute to the greenhouse effect when found in the troposphere, ammonia is not a significant greenhouse gas. Ozone is more often discussed in the context of the ozone layer, which protects the Earth from ultraviolet rays.
Oxygen and Nitrogen: These two gases are the most abundant in Earth's atmosphere. However, they are not greenhouse gases. Greenhouse gases are characterized by their ability to absorb infrared radiation and trap heat in the atmosphere. Oxygen and nitrogen do not have significant absorption bands in the infrared spectrum.
Nitrogen and Sulphur dioxide: Nitrogen, as mentioned, is not a greenhouse gas, and while sulphur dioxide can have climatic effects, it is not a major contributor to the greenhouse effect. Instead, sulphur dioxide plays a role in aerosol formation and acid rain.
Carbon dioxide and Methane: Both carbon dioxide (CO₂) and methane (CH₄) are potent greenhouse gases. Carbon dioxide is released primarily through fossil fuel combustion, deforestation, and various industrial processes. Methane is released from agriculture (especially rice fields), landfills, and during the production and transport of coal, oil, and natural gas. Both gases trap heat in the Earth's atmosphere, significantly contributing to global warming.

Based on the above analysis, the correct answer is Carbon dioxide and Methane. These gases are primarily responsible for the greenhouse effect resulting in global warming.

In conclusion, while several gases can impact the climate to varying degrees, carbon dioxide and methane are the principal contributors to the greenhouse effect due to their ability to trap heat effectively in the atmosphere.
