Correct option is B
The correct answer is (b) Infrared radiation.
Greenhouse gases in the atmosphere absorb most of the Earth's emitted infrared radiation, which heats the lower atmosphere.
This process is known as the greenhouse effect, which is essential for maintaining the Earth's temperature.
Key greenhouse gases include carbon dioxide, methane, and water vapor, which trap heat and prevent it from escaping into space.
Important Key Points:
Greenhouse gases absorb infrared radiation.
Heats the lower atmosphere.
Essential for maintaining Earth's temperature.
Key gases include carbon dioxide, methane, and water vapor.
Traps heat and prevents it from escaping into space.
Contributes to the greenhouse effect and climate change.
Knowledge Booster:
Ultraviolet radiation: Mostly absorbed by the ozone layer, not involved in the greenhouse effect.
Visible light: Passes through the atmosphere and is absorbed by the Earth's surface, but not trapped by greenhouse gases.
None of these: Incorrect, as infrared radiation is indeed absorbed by greenhouse gases.
