Why is it significant for the development of the theory of plate tectonics that paleomagnetic measurements in different locations indicate different north poles?

Significant in determining speed, direction and rotation of the continents.

Explanation:

Paleomagnetic measurements in different locations helps to understand the speed, direction and rotation of our continents. Recording and observation of magnetic reversals resulted in the sea floor spreading hypothesis. The volcano erupting from time to time, cools and solidifies the lava flow and this in  turn records the direction of the Earth's magnetic field. From geological studies of lava flow directions that has cooled and solidified, it has been noted that the North pole is not stationary but moved over time in a little bit. A simple explanation for this is that either the pole was stationary and the continent moved over time or the continent was stationary and the pole moved in a specified period of time.
