How does the location of Earth’s magnetic poles compare to the location of its geographic poles?
AThey are located at exactly the same points
BThey are located at noticeably different points and are not perfectly aligned
CEarth does not actually have magnetic poles
DThe magnetic poles are located at Earth's equator
Explanation
Earth’s magnetic poles, the points toward which a compass needle points, are located at noticeably different positions from its geographic poles, which are defined by Earth’s actual axis of rotation. This difference, known as magnetic declination, varies depending on location and also gradually shifts over time as Earth’s magnetic field slowly changes. Because of this discrepancy, navigators and mapmakers must account for the difference between magnetic north and true geographic north for accurate navigation.
