What does the Sun do at the North Pole?
As the text states, and you can confirm with the Activity below, the North Pole has essentially 6 months of daylight and 6 months of darkness. Because Earth is still rotating each day, this means you would see the Sun make a full circle of your horizon every 24 hours, but with a gradually changing altitude as days go by. More specifically: After 6 months of having the Sun below your horizon, you’d see the Sun circle around your horizon on the day of the March equinox. It would then continue to circle around each day, but would gradually circle higher until it reached a maximum altitude of 23 ½° on the June solstice. After that, the circling would continue but move gradually lower, putting the Sun back on the horizon on the September equinox. A similar pattern would then follow during the 6-month night, expect the Sun would always be below your horizon so you would not see it. But one more note: We said this is “essentially” what you’d see, but it’s not exactly what you’d see because Earth’s atmosphere bends and scatters sunlight. The bending means that the Sun still appears to be above the horizon even when it is actually slightly below it, and as a result the Sun appears to circle on or above the horizon for a few days more than 6 months (and to be below the horizon for a few days less than 6 months) each year. The scattering means that, just as you see any place on Earth, it is still a bit light — what we call twilight — for a while after the Sun sets. At the North Pole, the sunset is so gradual that there are several weeks of twilight before it becomes completely dark, and then several weeks of pre-dawn light before the Sun rises again in March.
