why does the sun go down earlier in the winter and much later in the summer?
In: Physics
The earth doesn’t circle around the sun straight up and down. During the year, the top half slowly leans closer to the sun than the bottom half. Then it happens again, but does it in reverse. If you could see the earth moving at high speed, it would look like it’s wobbling back and forth. Now think about this, there’s a sun side and a dark side to the earth (day and night). Because the top and bottom move, one gets more sunlight. More sun also shines on that one, so longer days. And because that half is closer to the sun, it gets hotter. That’s why we have long, hot summer days and long, cold winter nights. Another interesting fact is that the wobbling (also called tilt) is not very much. Just that little bit makes a huge difference. A bit more and you’d be able to go to a place where there was no night for most of the year, and one that was night most of the year. A little bit more and you’d have places that only had daytime and ones that only had nighttime. Fun stuff.
