    but I have a minor issue with the "tilt" of the earth. There is a 23 degree difference between the earth's axial plane and orbital plane, but it is misleading to say the earth is "tilted".

    When I was a child, a long long time ago, I was actually taught that the earth tilted on its axis twice a year, northern hemisphere towards the sun as summer approached then back away as winter approached. Silly once I came to understand the physics of inertia.

    Imagine the inertial force if a few trillion metric tons of mass actually "tilted" twice per orbit.

    Earth would be uninhabitable if it actually "tilted".

    Best way to explain why it's cold to a Conservative:

    It's WINTER you brain dead idiot!!! Ask the Australians if it's hot. And while you're thinking about it, ask yourself WHY it's been 20 years since it's been this cold? HMMMMMM????? Could it be a warming climate causing two decades to pass between record cold temperatures?

    We've been spelling it wrong all these years. It's actually: PRO-GOP-ANDA

    •  "Tilt" is a manner of speaking (1+ / 0-)

      It merely points out that the Earth's polar axis does not form a 90 degree angle in its orbit around the sun.  The "tilt" doesn't change; the north pole, and thus the northern hemisphere, points somewhat closer to the sun during half of the orbit, and somewhat further from the sun during the other half.  

      This is one of those basic facts that is widely misunderstood, even among highly educated people.  Many people will still say that the seasons are caused by how close the Earth is to the sun in its orbit.  Of course, if this were the case, seasons would be uniform over the globe, not the opposite in the Northern and Southern hemispheres.
