Answer to Question 1
ANSWER: False
Answer to Question 2
ANSWER: It is known that Earths magnetic field changes its polarity, or direction, with a long recurrence interval due to changes in currents in its core. New rock formed at divergent boundaries like the Mid-Atlantic Ridge records the polarity of Earths magnetic field. Observations of the recorded magnetic field in ridges around the Mid-Atlantic Ridge show that the stripes of alternating polarity surround the ridge. The conclusion is that the stripes represent rock created during different epochs of the magnetic field, demonstrating that the ridge is an area where new rock is created.
