The unique atmosphere allows life on Earth to exist. Earth's Atmosphere The atmosphere is divided into five layers with different characteristics. The ozone layer protects Earth from too much ultraviolet radiation, which can be harmful.

32. To return to the chapter summary click Escape or close this document. 2 2 Reviewing Main Ideas Earth receives its energy from the Sun. Some of this energy is reflected back into space, and some is absorbed. Energy Transfer in the Atmosphere Heat is distributed in Earth’s atmosphere by radiation, conduction, and convection.

33. To return to the chapter summary click Escape or close this document. 2 2 Reviewing Main Ideas Energy from the Sun powers the water cycle between the atmosphere and Earth’s surface. Unlike the atmosphere on Mars or Venus, Earth’s unique atmosphere maintains a balance between energy received and energy lost that keeps temperatures mild. This delicate balance allows life on Earth to exist. Energy Transfer in the Atmosphere

34. To return to the chapter summary click Escape or close this document. 3 3 Reviewing Main Ideas Because Earth’s surface is curved, not all areas receive the same amount of solar radiation. This uneven heating causes temperature differences at Earth’s surface. Air Movement Convection currents modified by the Coriolis effect produce Earth’s global winds.

35. To return to the chapter summary click Escape or close this document. 3 3 Reviewing Main Ideas The polar jet stream is a strong current of wind found in the upper troposphere. It forms at the boundary between cold, polar air and warm, tropical air. Air Movement Land breezes and sea breezes occur near the ocean.
