Question

Which of the following gases are called Greenhouse gases?
(a) Methane
(b) Nitrogen
(c) Carbon dioxide
(d) Both a and c​

Answer 1

Answer:

Carbon dioxide and nitrogen are called Greenhouse gases.

Therefore, option (d) is correct.

Explanation:

A greenhouse gas  is a gas that absorbs and emits energy within the thermal infrared range which causes the greenhouse effect.

The primary greenhouse gases in the atmosphere are:-

1. Carbon dioxide (CO₂),
2. Methane (CH₄)
3. Ozone (O₃).
4. Water vapor (H₂O),
5. Nitrous oxide (N₂O)

• Because of the greenhouse gases, the present average of earth is about 15 °C (59 °F). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F) .
• The greenhouses gases are also present in the atmospheres of Venus, Mars and Titan.

• Since the beginning of the Industrial Revolution have increased the atmospheric concentration of CO₂ by almost 50%. It is increased from 280 ppm in 1750 to 419 ppm in 2021.
• This increase has occurred even when the absorption of more than half of the emitted carbon dioxide by various natural carbon sinks in the carbon cycle.

Answer 2

(d) Both Methane and Carbon dioxide are called Greenhouse gases.

Greenhouse gases:

• A gas that produces the greenhouse effect by both absorbing and emitting radiant radiation in the thermal infrared range is referred to be a greenhouse gas.
• The five main greenhouse gases in the atmosphere of Earth are ozone, carbon dioxide, methane, and water vapor.
• Greenhouse gases on Earth trap heat in the atmosphere, warming the whole globe.
• The primary gases that cause the greenhouse effect are fluorinated gases, as well as naturally occurring gases such as carbon dioxide, methane, nitrous oxide, water vapor, and fluorinated gases (which are synthetic).

Greenhouse effect:

• The greenhouse effect is a phenomenon that happens when heat from a planet's host star passes through its atmosphere and heats the planet's surface but is prevented from radiating back into space by the atmosphere, making the planet warmer.
• Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space.
