Question
Use the excerpt from a sample research paper to answer the question.

The “greenhouse effect” is the process that occurs when the sun's heat becomes trapped in Earth's atmosphere. As explained in an article at the website of Smithsonian Magazine, the French mathematician Joseph Fourier is often credited as the first person to study this process. According to NASA, this process happens because the sun shines through the atmosphere during the day. It heats up Earth’s surface. At night, the surface cools, and the heat is released back into the air. However, some of the heat is trapped beneath a layer of carbon dioxide and other gases. The University Corporation for Atmospheric Research (UCAR) lists methane as one of the other gases that trap heat on Earth.
