Who beleives the tilt of the earth changes from year to year.For exsample during the northern hempheres winters the tilt of the earth in one year may increase by 1/10 of a dregree.The following year it may decrease by 1/10 of a dregree.The third year it may increase by 1/25 of a dregrees and change back again the following year.So is the tilit of the earth fluxuating from year to year.Could this be the first signs of a magnetic pole reversal.
It does change but it's too slow to be of any real consequence for the majority of people on this planet (only astronomers would actually care about it).
BTW: It has nothing to do with magnetic pole reversal whichanges earthch is something else entirely and which won't happen for a while (nor is it anything much to fear, unless you need a working compass or will have to take a lot of flights while there is no magnetosphere).
Or some things you think you know that just aren't so.
i belive it, it sounds correct
and google..and yea
If the tilt of the earth was changing, hundreds of thousands of amateur and professional Astronomers would know it instantly since the exact position if the North Star (Polaris) must be known in order to aim Equatorially Mounted telescopes.
Earth's tilt does change in a cyclical way. It's callechanges earthd nutation. The change is very small and slow so it's not enough to be noticeable on human timescales. It also very likely has nothing to do with pole reversal.
Sounds like you're describing what's called the "Chandler Wobble" (
The most widely accepted cause for the Chandler Wobble is changes in water pressure on the bottom of Earth's oceans which, if indeed true, rules out anything to do with the Earth's magnetic pole reversals. Those are almost certainly caused by fluctuations and other changes within Earth's molten core where the field itself is generated. (
