Earth Science Name: Chapter Seven--Worksheet Review # 1 Class Period: Section One: [Pages 166-172] Directions: Use your textbook and notes to assist you with answering the following questions. 1. Earth’s layers of rock are classified by their 1 and their 2 . 2. 3. If you were to dig to the center of the Earth, in what order would you encounter the three major layers? a. core, mantle, crust b. mantle, crust, core c. crust, mantle, core d. crust, core, mantle 4. What is the difference between oceanic and continental crust? 5. How is the lithosphere different from the asthenosphere? Choose the substance in Column B that best describes the composition of each Earth layer in Column A, and write the letter of the substance in the space provided. 10. True or False--The crust is the Earth’s only solid layer. Complete the table using page 168 as a guide. 16. Tectonic plates are part of the . 17. True or False--Tectonic plates move around on top of the asthenosphere. 18. Which of the following are characteristics of tectonic plates? (may have more than one answer) a. They are sitting still. b. They are different sizes. c. Some are made of oceanic crust. d. Some are made of continental crust. 19. True or False--The South American tectonic plate only has continental crust. 20. Why doesn’t continental crust sink below the oceanic crust? 21. produce seismic waves. 22. No one has ever seen the inside of the Earth. How have scientists determined its internal structure? 23. True or False--The inner core of the Earth is solid and made primarily of iron. 24. True or False--Temperature and pressure increase toward the center of the Earth. 25. True or False--The asthenosphere is the thinnest layer. Use the following terms to label the diagram below. Then use the terms to fill in the blanks in the sentences that follow. Terms may be used more than once.
