Correct Answer: Warming of the Earth because of trapping of radiations by the Earth's atmosphere
Solution : The correct option is Warming the Earth because of the trapping of radiation by the Earth's atmosphere
The greenhouse effect is a natural process in which greenhouse gases in the Earth's atmosphere trap heat from the sun. This stored heat warms the planet's surface and contributes to the planet's temperature remaining suitable for life. Even though the planet's natural greenhouse effect is essential to life as we know it, it has accelerated, resulting in climate change and global warming.
