This passage appears on a government website.

When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.

Based on this information, which activity is most likely to cause an increase in Earth’s surface temperature?

A.
littering, because this activity increases the amount of matter in landfills

B.
burning trash, because this activity adds heat energy to the atmosphere

C.
planting trees, because trees absorb greenhouse gasses

D.
burning fossil fuels, because this activity releases greenhouse gasses

D. burning fossil fuels, because this activity releases greenhouse gases.

Burning fossil fuels releases greenhouse gases such as carbon dioxide and methane into the atmosphere, which then absorb energy radiating from Earth's surface and contribute to the heating of the atmosphere and surface. This leads to an increase in Earth's surface temperature.
