Foldables Earth’s Atmospheric Layers Make the following Foldable to help you visualize the five layers of Earth’s atmosphere.
Foldables Collect 3 sheets of paper and layer them about 1.25 cm apart vertically. Keep the edges level.
Foldables Fold up the bottom edges of the paper to form 6 equal tabs.
Foldables Fold the paper and crease well to hold the tabs in place. Staple along the fold. Label each tab.
Foldables Find Main Ideas Label the tabs Earth’s Atmosphere, Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere from bottom to top as shown. As you read the chapter, write information about each layer of Earth’s atmosphere under the appropriate tab.
Reviewing Main Ideas 1 Earth's Atmosphere • Earth’s atmosphere is made up mostly of gases, with some suspended solids and liquids. The unique atmosphere allows life on Earth to exist. • The atmosphere is divided into five layers with different characteristics. • The ozone layer protects Earth from too much ultraviolet radiation, which can be harmful.
Reviewing Main Ideas 2 Energy Transfer in the Atmosphere • Earth receives its energy from the Sun. Some of this energy is reflected back into space, and some is absorbed. • Heat is distributed in Earth’s atmosphere by radiation, conduction, and convection.
Reviewing Main Ideas 2 Energy Transfer in the Atmosphere • 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.
Reviewing Main Ideas 3 Air Movement • 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. • Convection currents modified by the Coriolis effect produce Earth’s global winds.
Reviewing Main Ideas 3 Air Movement • 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. • Land breezes and sea breezes occur near the ocean.
Chapter Review Question 1 Which is the most abundant gas in the atmosphere? A. argon B. carbon dioxide C. nitrogen D. oxygen
Chapter Review Answer The answer is C. Nitrogen makes up 78 percent of the atmosphere.
Chapter Review Question 2 Which layer of Earth’s atmosphere is the highest above Earth’s surface? A. exosphere B. mesosphere C. stratosphere D. thermosphere
Chapter Review Answer The answer is A. The exosphere begins at 500 km above Earth’s surface.
Chapter Review Question 3 The layer of electrically charged particles in Earth’s atmosphere is called the __________. A. electrosphere B. exosphere C. ionosphere D. troposphere
Chapter Review Answer The answer is C. The ionosphere allows radio waves to travel across the country.
Chapter Review Question 4 What happens to the temperature in the mesosphere as altitude increases?
Chapter Review Answer As altitude increases in the mesosphere, temperature decreases.
Chapter Review Question 5 Why are chlorofluorocarbons thought to be important? Answer Because chlorine can destroy ozone molecules, it is thought that chlorofluorocarbon compounds may cause damage to the ozone layer in Earth’s atmosphere.
Standardized Test Practice Question 1 In which layer of Earth’s atmosphere would you find the ionosphere? A. exosphere B. mesosphere C. stratosphere D. troposphere
Standardized Test Practice Answer The answer is B. The ionosphere is found within the mesosphere and the thermosphere.
Standardized Test Practice Question 2 In which layer of earth’s atmosphere does temperature decrease as altitude increases? A. altisphere B. mesosphere C. terrasphere D. thermosphere
Standardized Test Practice Answer The answer is B. In the mesosphere, temperature decreases as altitude increases.
Standardized Test Practice Question 3 What is the total amount of incoming solar radiation that is absorbed? A. 15% B. 25% C. 50% D. 65%
Standardized Test Practice Answer The answer is D. Thirty-five percent of incoming solar radiation is reflected back into space.
