Use the internet or a book if you have to. Remember to site the source of your information. Use Wikipedia if
it is your only choice.
1. How far across is the entire Earth?
2. At what depth is the core/ mantle boundary? Does it have a name?
3. What makes up the “Lithosphere” and the “Asthenosphere”?
4. What portion of the Earth is partially melted?
5. In fraction form write out how much each layer encompasses. Example: the crust is 70km/6250km. Now
determine what percent of the whole each layer is equal to.
6. Is the “Rigid Mantle” a part of the crust?
7. How do you know that you have bones, a heart, lungs etc.?
8. Describe the density/ pressure/ and temperature of the composition of the Earth’s material as you gain
depth.
9. Which layer contains the most material?
10. What happens to the melting point of material at a depth of 5150km?
11. Why are there 2 different lines for melting point?
12. What is the difference between the continental crust and the oceanic crust? List two
differences.
13. Where and what are the convection currents? (p.17) Read this section.
14. How hot is the inner core?
15. What does melting point mean?
16. If the temperature of material is hotter than the melting point what should happen to it?
17. What is the outer core made of? What is the inner core made of?
18. What are the ranges of temperatures for the outer and inner cores?
19. Look at the answer for #10, why does the melting point cross the actual temperature?
20. What two things happen when you rub iron against iron? (p.13)
21. Just copying the answers from a friend does not make you smarter.
22. If one were to place a “widget” on a moving conveyor belt in a factory the expected outcome
would be…
23. If an object were to impede the progress of the “widget” what would happen?
24. Assuming the conveyor belt did not break or slow down, ever; draw a picture of the results to
the “widgets”.
25. What is the temperature at a depth of 1000km?
26. What is the temperature at a depth of 3000km?
27. What is the measurement of pressure for a depth of 2950km?
28. What is the measurement of pressure for a depth of 5150km?
29. How dense is the material of the Earth at a depth of 3000km?
30. How dense is the material of the Earth at a depth of 5000km?
31. At what depth is the “moho”? and what is it?
32. How do we know any of this information if we can not go down there?
33. Why can we not go down there? How far can we go?
