with rift valley Question 8 5 out of 5 points Here are some facts about magnetic polarity reversals in the Sun and Earth. -- Astronomers have detected magnetic field polarity reversals on the Sun. -- "With the same method that is used to determine sunspot polarity, scientists can also determine the global polarity of the Sun itself by looking at the part of the heliosphere above the magnetic poles. This has demonstrated that the entire solar magnetic field is reversing along with the polarity of the sunspots. " ( Source of these facts is ) Now, the fact that the Sun experiences magnetic field polarity reversal (the Sun's north magnetic pole trades places with its south magnetic pole) shows that a body much larger than Earth experiences magnetic polarity reversal. Hence, the notion is supported that magnetic reversals also can occur in the Earth's magnetic polarity.
