2. $100 Question from H1
Which layer acts as a giant magnet?

3. $100 Answer from H1 Inner solid core
The Iron and Nickel in the inner core gets magnetized by the movement of the outer core

4. $200 Question from H1
What is layer #1 and #2?

5. $200 Answer from H1 #1= Oceanic Crust #2= Continental Crus
We know this because oceanic is more dense and sinks under the continental.

Which layer is the convecting mantle? Draw a diagram to explain what happens in this layer.

7. $300 Answer from H1
Layer #4

8. $400 Question from H1
Which of the layers is a liquid made mostly of Iron and Nickel?

9. $400 Answer from H1
Layer #5
The outer liquid core

52. Final Jeopardy
Layer #3 was tested for Urnaium There is 25% of Uranium-274 remaining. We know that layer#3 is 60 million years old. What is Uranium-274’s half life?

53. Final Jeopardy Answer It has a half life of 30 million years.
25% left = 2 half lifes
60/2=30
