Name Date Class Chapter 4 PAGE KEELEY SCIENCE PROBES Temperature Changes in the Benchmark Practice Chapter Review Study Guide Inquiry Lab Note-taking Six friends hiked to the top of a tall mountain. They noticed the air was cooler on top of the mountain than at the bottom of the mountain. They wondered what happens to the atmosphere s temperature the higher and higher it is above Earth s surface. Frank: I think the farther the atmosphere is from Earth s surface, the colder it is. Julia: I think the farther the atmosphere is from Earth s surface, the warmer it is. Juanita: I think the atmosphere gradually cools to a certain altitude, then it gradually warms the farther it is from Earth s surface. Tyson: I think the atmosphere gradually warms to a certain altitude, then it gradually cools the farther it is from Earth s surface. Tilly: I think the atmosphere s temperature changes with each layer of the atmosphere. I think it can cool, warm, cool again, and warm again. Lyndon: I think the atmosphere cools for a while, but once it is at a certain altitude, it is at a constant temperature. Whom do you agree with the most? Explain why you agree. 122 Earth s

How does Earth s atmosphere affect life on Earth? Before you read the chapter, think about what you know about Earth s atmosphere. Record your thoughts in the first column. Pair with a partner, and discuss his or her thoughts. Write those thoughts in the second column. Then record what you both would like to share with the class in the third column.

Lesson 1 Describing Earth s LA.6.2.2.3, SC.6.E.7.9, SC.6.N.1.4, SC.6.N.2.1 Skim or scan the heading, boldfaced words, and pictures in the lesson. Identify or predict three facts you will learn from the lesson. Discuss your thoughts with a classmate. Importance of Earth s Define atmosphere, and identify four things the atmosphere does for Earth. : 1. Benchmark Practice Chapter Review Study Guide Inquiry Lab Note-taking Origins of Earth s 2. 3. 4. Write the number of each event on the time line to describe how Earth s atmosphere changed over time. 1. Photosynthetic organisms remove carbon dioxide from the air and release oxygen. 2. Water vapor cools and condenses. Rain falls, evaporates, and eventually accumulates in oceans. 3. contains present levels of carbon dioxide, oxygen, nitrogen, and other gases. 4. is mainly water vapor with a little carbon dioxide and nitrogen.

Lesson 1 Describing Earth s (continued) Composition of the Assess information about the atmosphere. Read each statement below. If the statement is true, write true on the line. If the statement is false, write false on the line and rewrite the underlined portion so that it is true. Earth s atmosphere is mostly made of visible gases, including nitrogen, oxygen, and carbon dioxide. Solid and liquid particles are also present in the atmosphere.

Lesson 1 Describing Earth s (continued) Identify the 2 layers of the atmosphere that contain the ionosphere. 1. 2. Explain, in your own words, how auroras form in the ionosphere. Air Pressure and Altitude Temperature and Altitude NGSSS Check How does temperature change as altitude increases? SC.6.E.7.5 Describe the relationship between altitude and air pressure. As altitude, air pressure. Identify the changes in temperature and altitude in the d ifferent layers of the atmosphere.
