Section 2: The Atmosphere
Read the passage below and answer the questions that follow
Solar energy reaches Earth as electromagnetic radiation, whichincludes visible light, infrared radiation, and ultraviolet light. Our planet only receives about two-billionths of this energy. This seemingly small amount of radiation contains a tremendous amount ofenergy, however. About half of the solar energy that enters the atmosphere passes through and reaches Earth’s surface. The rest of the energy is absorbed or reflected in the atmosphere by clouds, gases,and dust, or it is reflected by Earth’s surface. On a sunny day, rocks may become too hot to touch. If Earth’s surface continually absorbed energy, Earth would get hotter and hotter. Earth does notcontinue to get warmer, because the oceans and the land radiate the energy they have absorbed back into the atmosphere.
