Unit 3 Earth’s Atmosphere 3.1 Lesson 1 The Atmosphere p. 104 - 111 Essential Question: What is the atmosphere? Vocabulary: atmosphere a mixture of gases that surround a planet, moon, or other celestial body – air pressure the measure of the force with which air molecules push on a surface – thermosphere the uppermost layer of the atmosphere, in which temperature increases as altitude decrease – mesosphere the layer of the atmosphere between the stratosphere and the thermosphere and in which temperature – decreases as altitude increases stratosphere the layer of the atmosphere that is above the troposphere and in which temperature increases as altitude – increases troposphere the lowest layer of the atmosphere, in which temperature decreases at a constant rate as altitude – increases ozone layer the layer of the atmosphere at an altitude of 15 to 40 km in which ozone absorbs ultraviolet solar radiation – greenhouse effect the warming of the surface and lower atmosphere that occurs when water vapor, carbon dioxide, – and other gases absorb and reradiate thermal energy Lesson 1 The Atmosphere What is Earth’s atmosphere? A Mixture of and Small Particles How do pressure and temperature change in the atmosphere? What are the layers of the atmosphere? Thermosphere Mesosphere Stratosphere Troposphere How does the atmosphere protect life on By Absorbing or Reflecting Harmful Radiation By Maintaining the Right Temperature Range
