What causes the greenhouse effect?
What will be an ideal response?
The greenhouse effect occurs when some of the solar energy absorbed by the earth radiates into the atmosphere as infrared radiation (heat). As this radiation interacts with molecules of several greenhouse gases in the air, it increases their kinetic energy and warms the lower atmosphere and the earth's surface.
