The equator is the circle where the Sun is directly overhead at noon on the equinoxes (September 22, March 22). ... So above the Arctic Circle, there is a certain amount of time during the winter when the sun remains below the horizon. The same is true of the Antarctic Circle during the Southern Hemisphere winter. For everywhere within the Arctic Circle, there is at least twenty-four hours of continuous daylight on the Summer Solstice in June, and at least twenty-four hours of continuous nighttime on the Winter Solstice in December. That is to say, there is one whole day during which the sun does not set, and one whole day during which the sun does not rise. This is because the earth is tilted at a 23.5 degree angle, and during the winter solstice, the northern hemisphere is tilted away from the Sun, meaning that the Arctic Circle is completely tilted away from the Sun, at that time it experiences 24 hour nighttime, and vice versa for the Antarctic Circle. As you can see there are 5 major lines that cross the Earth, (all imaginary, but very helpful). The light and shadow created by the Sun helps us to see where the Earth experiences direct light from the sun and indirect light because we are a sphere. Where there is shadow, there is no sun or light from the sun at all to the person who is standing in the shadow. If you look up north you can see that the shadow starts right at the Arctic Circle line. Below the Antarctic Circle line is right at the end of the light before it goes to shadow. They're the boundaries of the areas around the poles where it's possible for the sun to stay up (and down) for a full 24 hours or more. OR Why are the circles where they say they are? You don’t need to use math if you happen to be standing at that point, on the imaginary line, during the winter solstice where the sunset lasts a whole day, and you can see it for yourself, but as with most things math and numbers can help you see the reason for things better. The Equator and Poles are 90 degrees apart. The tilt of the Earth is 23.5 degrees so with 90° subtracting 23.5° you get 66.5°. The Arctic Circle is 66.5 degrees north and the Antarctic Circle is 66.5 degrees south....I thought the math would actually help....

Wow that girl in the bathing suit is weird ....... Anyway I hope I do not write as long of a paragraph as I normally do. It would be really cold to live in a place that is always with no sun. I would also not like it if the sun never went down.....

Dang! I was so close to getting first! Anywho, I think it would be kind of cool to see what exactly 12 hours of day and night would be like. Like what if you had to live like that forever? Also, Errol, sometimes I try to get 2 pieces of candy but it's not like I'll get all upset or eat up all my time doing it.

can there be a lunar and solar eclipse on mars? I checked it but i guess the moons are to small for mars to see an eclipse. but the other planets can (Jupiter, Saturn, Uranus, Neptune)

I think it would be fun to live in the north and South Pole. You just have to prepare for hibernation... Thanks Mrs.Taylor for the blog post today! Very helpful! Hope our presentations go well tomorrow!

wow lily, I'm surprised that you wanted to not write a paragraph. [or an essay.] and I agree with Errol I really really really really want our posters to go well. and Errol, sometimes Mary grace writes paragraphs to, and gets 2 candy's. and I like writing paragraphs for 1 piece of candy, 2 pieces of candy or none. but sometimes I don't have time to write a paragraph, so I only get one piece of candy, 'cause I only have time to write a sentence. well, got to go, bye!!!!!!!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
