Question

Quizplus · Accepted Answer

The greenhouse effect is the natural process by which certain gases, such as carbon dioxide, water vapor, and methane, trap heat in the Earth's atmosphere, keeping our planet warm enough to support life. Without the greenhouse effect, the Earth's average temperature would be -23 degrees Celsius, which is too cold to support most forms of life. Therefore, option B is the best choice. The other options are not necessarily true as they oversimplify complex issues related to climate change and ozone depletion. The greenhouse effect is what makes Earth's average temperature a comfortable 15 degrees Celsius. Without it, the average temperature would be a frigid -23 degrees Celsius, making most of the planet uninhabitable.
