Name Date Hour Investigating Earth s Interior While at each station, complete the prompts below. Be sure to follow all directions and to read carefully. STATION 1 Pie Slice Using your pie slice of the Earth answer the questions that follow: 1. Which layer is the thinnest? 2. Which layer is the thickest? 3. Which layer is the hottest? 4. Which layers are solid? 5. Which layers are liquid? 6. Which layer is the least dense? List the Density: 7. Which layer is the densest? List the Density: 8. 45% of the crust is continental crust, while 55% is. 9. What do you notice about temperature as you move from the outer layers towards the center? 10. Pressure increases as you travel from the crust to the center of the Earth. This is a result of the weight of the rock above. Why would the temperature increase? When finished, feel free to browse through the Science World magazine. STATION 2 Video Overview and a Focus on the Core Scan the QR Code and view the video. As you view, answer the questions below. 11. What causes the different layers inside the Earth? 12. What 2 events allow us to see what s inside Earth? 13. Name the 3 chemical layers of the Earth mentioned in the video, and name the 5 mechanical layers, mentioned in the video, of the Earth. We will work with names from both categories through this unit.

14. What is the symbol for iron? 15. Why is iron and nickel found at Earth s center, while aluminum and silicon are found near Earth s surface? 16. Why is the inner core most likely solid? 17. Why is the outer core most likely liquid? 18. Why is the liquid outer metal core so important to our survival? 19. True or False Overall, inner Earth is currently warming. 20. Complete the Venn diagram using the phrases below: Solid metal, iron, dense ball, molten metal, nickel, liquid layer Inner Core Outer Core STATION 3 The Crust Using prior knowledge, the specimens at the table, and the information found on page 51 of the textbook, answer the questions that follow: 21. True or False. The crust does not include the ocean floor. 22. Where is the crust the thickest? Thinnest? 23. Look at the rocks found at the station and your pie piece... a. Which rock is most like the rock found beneath the ocean? A or B b. What is the name of the type of rock found beneath the ocean? c. Which rock is most like the rock that makes up continental crust? A or B d. What is the name of the type of rock that makes up most continental crust? e. and are the most commonly found elements in the crust. 24. Label the continental and oceanic crust on the drawing. When finished, feel free to browse through the Science World magazine. 2
STATION 4 The Mantle The mantle can be broken down into several sections or parts. These parts include the lithosphere, asthenosphere, and upper/lower mantle (mesosphere). Do you know the difference between these parts? Turn to page 53 and using the information found here, answer the questions that follow: 25. Label the drawing using the following terms (some of the terms will be used more than once): mantle, lithosphere, asthenosphere, upper/lower mantle STATION 4 Continues Next Page 3
26. Sort the cards using the information found in the text and above. Copy into the chart below. Mantle Found immediately below crust. This thick middle layer is a solid part of the Earth. There is more Fe and Mg than what you find in oceanic crust. It is rock and denser than oceanic crust. Name Features Found in the Uppermost Mantle: Part of the Middle Mantle: : (Mesosphere) STATION 5 Working with Graphs Numbers and graphs are always an important part of science. What can a graph tell you about Earth s interior? Answer the questions below using the graphs found at the station. 27. What is the symbol for Aluminum and Iron? 28. Which 2 elements are most abundant in Earth s crust? 29. What percentage of Earth s crust is oxygen and silicon? 30. 2.8% of Earth s crust is. Station 5 Continues Next Page 4
31. Which graph shows how temperatures change between Earth s surface and the core. 32. Between what depths does Earth s temperature increase the slowest? 33. Why does the line graph show a temperature of 16 C at 0 meters of depth? 34. How does temperature change with depth in Earth s interior? 35. If you traveled to a depth of 1,500 km, what temperature would you experience? 36. At what depth would you get a temperature reading of 3,000? 37. Scan the QR Code to the right. Watch and list what you found interesting. 38. Scan the QR Code to the right. Watch and list what you found interesting. 5
