why is earth magnetic north moving toward russia at a rate 40 miles per year and what is the outcome
The earth's magnetic field has always wandered relative to the north pole (axis of spin) and ocean navigators have had to make magnetic corrections to compass readings. Forty miles per year is still a small part of the earth's circumference but navigators need as much accuracy as possible and charts may become obsolete (as re magnetic corrections) sooner than expected if wandering is excessive.
the magnetic field is a dynamic phenomenon. It is produced by motion of materials deep inside the earth; the process is complex and involves a lot of chaotic behavior. As a result, the motion inside the earth, and the resultant magnetic field, are variable. This results in the migration of the field relative to fixed earth surface reference points. As with any complex motion, direct extrapolation of a short term historic pattern to derive a prediction of future position often results in an incorrect prediction. For example, you state that the pole is migrating toward Russia at a rate of 40 miles per year, and thus the simplest way to predict would be to assume a linear and constant change. Unfortunately, the field does not display either linear or constant change in position, so the further into the future you extrapolate the current trend, the less accurate your prediction is likely to be. Position change is neither constant nor linear. You wouldn't predict the coastline to be 500 miles inland if you observed sea level change of one meter per hour as the tide is coming in, and the tide is a very simple and regular phenomenon, albeit non-linear. You know enough to be certain that the trend will not maintain itself. The same sort of thinking applies to pole position, except, of course, the change is a far more complex phenomenon than sea level variation with tides.
the earth is on a tilt of 23 degrees. Throughout the year it gets moved those miles this causes the seasons.
