they are both the same distance away from the equator and from the poles. both circles are at 66 1/2 degrees. also they both form imaginary line borders of polar regions.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.

polar areas, such as antarctica or the south pole.
