We are technically in autumn, but we've had such unseasonably warm weather that some of my trees think it's spring. It would not be inconceivable for me to enter both challenges if it was allowed. Now if I could just find a DECENT subject for an autumn photo...
I wonder what percent of the active members of DPC are in Southern hemisphere (autumn) and what percent in the Northern (spring)? I presume that the autumn challenge will be a bit more crowded.

There's way more people in the northern hemisphere... I was actually thinking that maybe I should enter autumn instead -- but I have my ideas for spring already.
i did, but it was one of those things you learn in school but forget since it doesn't really apply to you. i knew the southern hemisphere had the seasons opposite, but i wasn't sure to what extent that existed, ie fall foliage and all.
The earth is closer to the sun when we have winter here in the US, but its the indirect sunlight that controls the dominance of the season. The sun is closer during the summer months in the southern hemisphere so i wasn't sure which played a more crucial role there.

The Earth's tilt is what causes the seasons rather than the distance from the Sun, in the northern hemispheres winter the northern hemisphere is tilted away from the sun and so receives less solar energy.
Yeah but he learned manners instead of useless trivia.
Ah yes, geography. I always hated that part of the useless trivia curriculum at school.
You assume that what you were taught in geography was taught everywhere.
I never took geography in high school, only the snippets we got in elementary school... and that was not covered. I learned some of it in Astronomy, but that was an elective that not everyone took.

And IIRC, we're closer to the sun in the winter than the summer.

That is correct, also I believe we are closest to the sun in spring and autumn.
FWIW, perihelion (closest approach of Earth to the Sun) currently occurs around Jan 3, and aphelion (greatest Earth-Sun distance) around July 4. These dates change over time, on an approx. 21,000-year cycle.
The Earth's tilt also changes over time, ranging from 22.1 to 24.5 degrees, oscillating on a 41,000year cycle. It's currently 23.44 degrees, and getting smaller.

Curious, what age does elementary school go up to? Here in the UK all children study geography from age 5 through to age 14 at which point they make their GCSE course selections, and may drop it. I always find the differences in education between different countries interesting.

When I was in school, Elementary was 1-7 grades (6-13 or so in age). High school was 8-12. Some counties had middle schools then so it was 1-5 was elementary, 6-8 was middle and 9-12 was high school.
That's the way most here in Georgia are now.
We would study some geography as part of social studies, history, etc... but not as a specific "get our your geography book" kind of lesson.
In High School, World Geography was a suggested course if you could arrange it. My kids did not take it in high school because they needed that slot for a different elective.
