Woooooot.

Yay, exam-o is over-o. IT took me 20 minutes, and I read every question carefully, checked my answers twice and all that jazz. I think I might have gotten very near 100%. OH JOY. I know it's only a multi-choice quiz worth 10%, but it'd be so nice to say "I got 100% in this exam thing I did" (even though I've been lolling about how lame/insignificant this exam is all year)
The only question I'm slightly worried about is a question that was about why we have seasonal variation in climate. The one I picked said it was to do with the axial orbit or something and blah blah, and the other one said it was the earth's circular orbit around the sun, with distance changing and blah blah. Now, I didn't' pick this one because I thought it might have been a trap question, because in a past exam it said the Earth's Elliptical orbit, which is actually right, and would in fact change the temperature, whereas if the Earth's orbit was circular, there would be no difference in distance from the sun. You see? So I hope that I'm right and it was a trap answer, and not just a typo, because that would mean that I lose markies :(
That is all!
I just realised Bonnie will be 16 when I'm 23, which made me very sad, so I went out to play fetch with her, but she totally snubbed me/the ball. :( funny Bonnie.

Forgive me, but isn't the change in seasons due to the rotation of the earth around the sun, and the amount of light that each hemisphere gets, not the shape of it's orbit? Otherwise how can you have summer twice a year? and how can in be concurrent with winter? (once in the northern hemisphere, and once in the south)

I think so, but I also think I remembered the question incorrectly in that entry ^_^ I looked up the question in that past exam again, and the answers were either distance between earth and sun changing, because of the circular orbit, or axial tilt changing the angle that radiation strikes the planet from season to season, which changes the amount of energy transmitted from the sun.
So I think that the first option is wrong, because of the way it was worded - a circular orbit wouldn't cause variation in the distance from the sun.
So I'm a bit more convinced it would be the axial position now, especially with what you pointed out, because the tilt is (I think) what causes one hemisphere of the earth to be shaded more while the other gets more light... Do you agree?
