Which of these processes has a cooling effect on earth? a. as snow and ice melt, the underlying surfaces absorb heat from solar radiation. b. when permafrost melts, methane is released into the atmosphere. c. burning fossil fuels increases the concentration of greenhouse gases in the atmosphere. d. rising carbon dioxide levels fuel the growth of algae and plants, which increases carbon dioxide absorption.

The correct answer is D. Rising carbon dioxide levels fuel the growth of algae and plants, which increases carbon dioxide absorption.

This is due to the fact that the more carbon dioxide there is for the algae and plants, they will consume it as much as they can, releasing oxygen in the atmosphere, the oxygen cools off the Earth, and as that trend continues and gets on a bigger scale, the Earth will cool off significantly.

It is c. naturally in the environment
