>winter is December, January and February in the northern hemisphere, isn't it? (it's the opposite for me, dec/jan/feb is summer)
What the fuck. Someone posted this on the Pokemon board. I doubt I went all my life without realizing that in Canada winter is December January February. But in the Southern hemisphere December is Summer.
Is that true? Am I retarded? How do seasons work?

Yes, you are a retard.

Sorry dude I just forgot some basic stuff. Help me remember.
The earth rotates about an axis, but the axis also rotates.
Is it because the axis rotates that we have season or the oval orbit of the Earth?
When it's winter at one point on the sphere, is it summer on the opposite point?

The Earth rotates around the Sun. The axis does not rotate.
The seasons line up with the different parts of the year because the tilt does not rotate (in some time periods the tilt will expose some part of the planet to the Sun more often than in other time periods).
Look at one of those moving models of the planets orbiting the Sun and pay attention to the tilt.

No axial tilt has no affect whatsoever on seasons. Seasons depend on earth's distance from the sun. Note earth has a elliptical orbit so earth is closer to the sun at certain times and farther at the other times and those times correspond to the seasons. The myth that tilt causes seasons has been proven false by Kepler hundreds of years ago. Anyone who denies this is a shill.

The cycle is 26k years long, though.

The Earth's seasons aren't caused by the distance from the Sun you myth-perpetuating shill.

>>winter is December, January and February
>winter is December January February
Winter in the northern hemisphere begins on the winter solstice, about December 21st, and runs through the vernal equinox, March 20th or so.
So most of December is fall, not winter, and most of March is winter, not spring.

That's just wrong.
If it were true, Australia and Canada would have winter at the same time, and they just don't.

>those times correspond to the seasons
True, but probably not how you think it does:
Aphelion is in early July (northern summer)
Perihelion is in early January (southern summer)
Southern hemisphere gets more solar radiation (about 7% IIRC)

Direct light = hotter.
Shit aint complicated
Well guys.
I'm more confused than when I started.
I'll try google answers. Maybe a nasa for kids page.
