Because the earth tilts, so in summer one pole can turn towards the sun and in winter turn away drøm the sun.
The earth tilts as it wobbles its way through the universe, tilting the poles toward and away from the sun.
12 hours each on average, same as anywhere else on Earth. At the poles there is six months of day during the summer and six months of night during the winter, but it's still 12 hours per day on average.
The sun is above the horizon for 6 months and below the horizon for 6 months, only at the earth's north and south poles. Those points aren't part of any countries.
Alaska
The sun is vertically overhead at the equator in the months March 21st to September 23rd.All places on Earth, (except at the poles) receive 12 hours of daylight (day) and 12 hours of darkness (night). Days and nights which are 12 hours long are called equinoxes.Note: Day and Night are always 12 hours long at the Equator.
Because It does
because the earth is tilted towards the poles,so in summers the north pole will have continuous daylight for 6 months and south pole will have night for 6 months.Then in winters it will be reversed i.e. north pole will have night for the other 6 months and south pole will have continuous day light for 6 months. this proves that the poles experience day for 6 months and other 6 months they experience night.
Only at the Earth's north and south poles.
No. This only occurs at the poles. Northern Norway (Svalbard) has 5 months of continuous daylight from mid-April to September and 5 months continuous night from late October to March.
This phenomenon occurs in no country on Earth. At the poles, however, the sun rises and sets once each year. There are no countries at the poles.
No city, but that happens at the north and south poles.
Sun does not rise in Greenland for several months because it is near to North pole and at the poles there is night for 6 months and day for 6 months. At the poles the day and night are so long because there is a tilt in earths axis then when earth have went around the half one pole hides and the other pole is in light.
The earth tilts as it wobbles its way through the universe, tilting the poles toward and away from the sun.
Because the poles tilt towards the sun in summer the North and South Poles have six months when the sun is visible day and night.
Only regions north of the Arctic Circle, or south of the Antarctic circle, will experience at least one day without sunlight during the year. The closer one gets to the pole, the more days will occur without sunrise, and conversely the same number without a sunset. At either of the poles, there is 6 months of daylight and 6 months of night. The equinoxes are the starting and ending of the polar day/night, so the farther away from the poles, the later in the season the day of no sunlight will occur, and the earlier the day of no night.
12 hours each on average, same as anywhere else on Earth. At the poles there is six months of day during the summer and six months of night during the winter, but it's still 12 hours per day on average.
No. Day and night are DEFINED based on the sun. Generally, it is day when the sun is shining on a part of the world, and night in the part it isn't shining- yes, that does mean that while it is day somewhere on earth, it is also night somewhere else. Day and night are determined by the Earth Rotating on it's axis. As one side of the Earth is facing the sun and experiencing daylight the opposite side is facing away from the sun and experiencing night time. The Earth's axial tilt causes extremes at the poles where the sun shines continuously for several months or is blocked by the rest of the Earth causing night time for several months. So the North and South poles can experience a 24hr period with only light or only dark.
