5. Which of the following is not true of solar energy reaching the earth?
6. Carbon dioxide, water vapor, and ozone in the atmosphere naturally trap some of the light that reflects back from the earth's surface. The light is converted to heat, with the gases acting as insulating blankets. This natural process warms the earth enough to support life. This process is called
