Question 3

Question
If you look at magnetite which is close to the mid-ocean ridge. What do you expect about its alignment?
Answer
  • They're aligned in a way that you would expect with the current magnetic field

  • They're aligned in a way that you would expect with the ancient magnetic field

Question 4

Question
And what about if magnetite is further?
Answer
  • You have circles of other magnetic rock that is going in the opposite direction
  • You have stripes of other magmatic rock that is going in the same direction
  • You have stripes of other magnetic rock that is going in the opposite direction

Question 5

Question
Why this magnetic stripes pattern is an evidence of plate movement?
Answer
  • Wegener discovered them
  • The rift has had to move apart
  • Magnetic stripes change throughout time

Question 6

Question
In present times, What system do we use to measure the plate movement?,
Answer
  • Lageos
  • Computer monitoring
  • GPS satellites
