Which statement is true regarding the gas carbon dioxide?
Review of the options:
The rays of the sun (yellow arrows) pass through the atmosphere (grey line) and reach the earth. Much of the heat is absorbed (red dots) and the excess bounces off the earth’s surface and is reflected back out into space (red arrows).
The car releases emissions into the atmosphere, which makes it thicker. When the atmosphere gets thicker, some of the heat rays reflected back from the surface cannot get through. These rays instead bounce back towards the earth while emitting more heat. In other words, the earth is getting warmer than it otherwise would.
