What Causes Global Warming?
Global Warming- an increase in the Earth's average surface temperature.
Our earth is heated by the rays of the sun. As the sun shines down on us, energy from the heat reflects off of the earth, into space. Gases from the atmosphere take this energy and reheat the earth. This is called the "greenhouse gas" effect. This is caused by water vapor and carbon dioxide, with the rest heated by other gases.
