6th Grade-Ch. 1 Sec. 3 Magnetic Earth Presentation Transcript

  • 1. Ch. 1 Sec. 3 Magnetic Earth
  • 2. compass
    • device that has a magnetized needle that can spin freely
  • 3. Just like a bar magnet, Earth has a magnetic field surrounding it and 2 magnetic poles.
  • 4.  
  • 5. Circulation of molten material in Earth’s core causes Earth’s magnetism
  • 6. Earth’s magnetic field 2:04
  • 7.
    • in northern Canada- about 1,250 km from geographic North Pole
    magnetic North Pole
  • 8. magnetic declination
    • angle between geographic north and the north to which a compass needle points
  • 9. Earth produces strong magnetic field  can make magnets from ferromagnetic materials
  • 10. Van Allen belts
    • 2 doughnut shaped regions located 1,000 - 25,000 km above Earth’s surface
    • contain electrons & protons traveling at very high speeds
  • 11. solar wind
    • stream of electrically charged particles flowing at high speeds from the sun
  • 12. The Solar Wind [00:38]
  • 13. magnetosphere
    • region of Earth’s magnetic field shaped by the solar wind
  • 14.
    • glowing region caused by charged particles from Sun
    aurora
  • 15.
    • northern hemisphere= Northern Lights (aurora borealis)
    • southern hemisphere= Southern Lights (aurora australis)
  • 16.  
  • 17.  
  • 18. The Northern Lights: Aurora Borealis [01:59]
  • 19. Review Time
  • 20. magnetosphere
    • region of Earth’s magnetic field shaped by the solar wind
  • 21. magnetic declination
    • angle between geographic north and the north to which a compass needle points
  • 22. How are Earth and a bar magnet similar?
    • Both have a magnetic field surrounding it and two magnetic poles.
  • 23.
    • glowing region caused by charged particles from Sun
    aurora
  • 24. Van Allen belts
    • 2 doughnut shaped regions located 1,000 - 25,000 km above Earth’s surface
    • contain electrons & protons traveling at very high speeds
  • 25. compass
    • device that has a magnetized needle that can spin freely
  • 26.
    • northern hemisphere= Northern Lights
    • aurora borealis
