The North Pole is currently off the coast of Canada, but it has moved over time due to Earth's magnetic field and the shifting of groundwater. The axis of rotation of the Earth has also shifted due to human activity, specifically the pumping of groundwater from below the surface. These changes have implications for navigation and the Earth's magnetosphere, which protects us from solar radiation.
1. The North Pole is off the coast of Canada and not a fixed point.
2. The Magnetic North Pole is moving at 37 miles per year and heading towards Siberia.
3. Earth's magnetic field is created by the flow of multi-magnetic materials in Earth's outer core.
4. Earth's magnetic poles have reversed 183 times in the last 83 million years.
5. The Earth's axis is shifting location due to groundwater extraction by humans.
6. The shift in the Earth's rotational axis corresponds to a shift in the location of celestial objects observed through radio telescopes.
7. The shift in the Earth's axis due to groundwater extraction is probably permanent.
