1.3 Magnetic Earth Csrq Notes

  1. 1. 1.3-Magnet Earth-Pages 22-27N Journal Page 13 CSRQ Reading Guide-follow the correct form for writing these answers in your journal 1. Who studied compasses in the 1500’s? What was his hypothesis? Was his hypothesis correct? How do you know? 2. How is the earth similar to a bar magnet? 3. What did Gilbert assume made up the core of the earth? Was this true? What is in the core of the earth? How does this help the earth create a magnetic field? 4. Are the earth’s magnetic poles the same as the geographic poles? Give a precise example. 5. What is magnetic declination and why is important that navigators understand this term? Is magnetic declination fixed or does it change? 6. How does earth form magnets out of ferromagnetic material? 7. Explain how earth leaves a record of the magnetic field. What does this record tell us about the magnetic field of the earth? 8. What is the magnetosphere and how is this area shaped by solar winds? What are the Van Allen Belts? 9. What happens when particles from solar winds penetrate earth’s magnetic field at the poles? 1.3-Magnet Earth-Pages 22-27N Journal Page 13 CSRQ Reading Guide-follow the correct form for writing these answers in your journal 1.
