Is polar wander the same as polar wandering, and which term is correct?
Answer
The proper term is polar wandering, which describes the fact that Earth’s magnetic poles have moved over the surface of the globe during the past 30 million years. The north magnetic pole is presently located off the western coast of Bathurst Island, in the Canadian Northwest Territories, almost 800 miles northwest of Hudson Bay. The south magnetic pole is presently situated at the edge of the Antarctic continent in Adelie Coast, about 1,200 miles northeast of Little America. Even over short spans of time the position of the magnetic poles is not constant and shows a measurable, though very small change, from year to year.
