The Earth’s rotation is gradually slowing at approximately 17 milliseconds per hundred years although the rate at which it occur is not perfectly uniform – This has the effect of lengthening our days but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.

The magnetic field protects the Earth from the effects of solar wind.
