the magnetic poles are thought to shift, not that the earth and its corresponding wobble magically flip upside down you idiot

I'm not saying that it would flip upside down, I'm just asking if the angle change would affect the seasons.

op is that image real

>>3844780
Yes.

where can I purchase instant katz? they always take so long to cook so some instant ones would be nice

you idiot that's a fake box

also sapg is dead

Seasons are a function of the distance of the Earth to the Sun, it doesn't have to anything with the magnetic configuration of the planet itself.

Seasons are not related to the magnetic poles, I'm afraid. Nor are they actually to do with the distance to the Sun - close but no cigar - Earth's orbit is very close to circular, and actually is slightly further away during Northern hemisphere's summer months.

Actually they are to do with the angle of the Earth's rotational axis (not magnetic axis). So when your hemisphere is tilted towards the Sun during the day, you get longer days of more direct heating, hotter weather, summer. In the winter, the reverse happens and the days are shorter with a shallower illumination.

The inversion of the magnetic polarity would cause some weather effects, but they would be more to do with the interaction of the magnetic field and the solar wind; radiation etc.

No. Seasons relate to axial tilt, not the distance to the sun.

>he thinks seasons are due to the elliptical orbit of the earth around the sun.

thats basically what I'm trying to say. I dunno where the magnetic shit came from, I guess I could have worded it better myself though.


I am referring to the axial tilt. does it's moving every ~26000 years have an effect on the seasons?

not who you're replying to, but yes it does. i believe what you are specifically referring to is called precession (wobble of earth on it's axis). a combination of the earth's motions induce ice ages, these are known as milankovitch cycles. i believe ice ages happen when there is cool summers and warmish (relative) winters. i could be wrong about that though, it's been a while.

13,000 years ago, when the earth was at its current point in its orbit around the sun, the seasons were opposite what they are right now. However the only noticeable effect this has was the relationship between the positions of stars in the sky and the seasons.

We're not talking about the magnetic pole. We're talking about the rotation axis.

To continue, in ancient times, people figured out what time of year it was by getting up before sunrise and seeing which stars were on the horizon before the sun came up. This is a way of seeing where the earth is in its orbit, but of course the ancient people didn't know that. They used twelve constellations the sun could be in to tell you what approximate time of year it was. That's where we get the Zodiac.

Over thousands of years, the constellation you see the sun in during a particular season changes due to the earth's rotation axis precessing. The full cycle takes about 25,000 years.

sorry, 26000 years.
