What is the greenhouse effect, and how does it work? What happens when greenhouse gas levels in the
atmosphere increase? What will be an ideal response?
Carbon dioxide and other greenhouse gases are natural components of the atmosphere. These gases
allow sunlight to pass through the atmosphere but trap some of the heat that radiates outward from
Earth's surface. This is the greenhouse effect. If the mount of greenhouse gases in the atmosphere
increases, they can trap more heat, and the atmosphere warms.
