How many days are all dark in Antarctica, and is there a difference between day and night in the Sou

Polar Day. Polar night is a unique natural phenomenon in the Polar Circle, and the polar day and polar night are special natural phenomena that are the earth's axis along the slope.

The result of rotation. That is, the Earth rotates.

The time-to-earth axis is inclined to the perpendicular line at an approximate angle.

Thus the earth is in orbit around the sun for six months, and one pole of the south and north poles is always facing the sun, and the other pole is always facing away from the sun; If the South Pole is facing the Sun, the South Pole will be all day, no night for half a year; At this time, the North Pole does not see the sun, and the North Pole is all night for half a year, and there is no day. In the next half year, it is the opposite, the North Pole is facing the Sun, and the North Pole is all daytime; At the South Pole, the sun is not visible, and the South Pole is all night. In areas within the Polar Circle, the length of the polar day and polar night varies depending on the latitude.

Polar day: In the Antarctic region.

The sun never sinks into the horizon for 24 hours local time.

The phenomenon is called polar day. At the South Pole, half of the year is the polar day; If refraction is taken into account, it should be a little more than half a year. The polar day at the South Pole occurs during the summer half of the Southern Hemisphere.

Polar Night: In contrast to the polar day, in the Antarctic region, the phenomenon that the sun is always below the horizon for 24 hours local time is called polar night. At the South Pole, half of the year should be the polar night; If refraction is considered, it should be less than half a year.

The polar night at the South Pole occurs at the exact opposite of the polar day, during the winter in the Southern Hemisphere.

In Antarctica, the duration of the polar day and the polar night becomes shorter as the latitude decreases, and on the Polar Circle, the polar day and the polar night occur for only one day.

At the North Pole, the polar day is seven days longer than the polar day at the South Pole, because the North Pole is what we call summer, when the Earth is in orbit at aphelion.

Neighborhood; Conversely, the Antarctic Pole Day is winter, when the Earth is near perihelion. The Earth's orbital speed is greater at perihelion than at aphelion, so the South Pole Day ends faster than the North Pole Day. Similarly, the polar night at the North Pole is 7 days shorter than the polar night at the South Pole.

Only in the winter did it rise back to the size of the United States. There are dark nights at the North and South Poles, and the South Pole has 135 days a year, that is, four and a half months of continuous full nights, while the North Pole has a direct sun at the equator around March 21 every year, and the North Pole sun does not set all day. The day ends 24 hours a day, and the day at the North Pole does not end until around September 23, when the sun shines directly past the equator again.

The Arctic night lasted 191 days. But the sun shines directly in the southern hemisphere, and the north pole begins to sunrise all day long. Spend 24 hours a day in the dark.

The number of black days that lasts in the North Pole is 174 days, so it can also be said that one year at the North and South Poles is equal to one day and night, but the day and night at the North and South Poles are exactly the opposite.

Theoretically, except for the poles of the North and South Poles, there is a division of day and night everywhere else. Taking the North Pole as an example, when the sun begins to move northward from the equator, the area north of the Arctic Circle begins to gradually enter a state of long days and short nights, and the North Pole is the polar day. When the Sun moves to the Tropic of Capricorn, the entire Arctic Circle is polar daylight; When the sun then moves southward, the Arctic Circle is daytime! It is gradually shortened until the sun moves to the equator, and the day and night are of equal length.

When the sun begins to move south from the equator, the region north of the Arctic Circle begins to enter a state of short days and long nights, with the North Pole being the polar night; When the sun moves to the Tropic of Capricorn, it is polar night throughout the Arctic Circle; As the Sun then moves northward, the days within the Arctic Circle begin to lengthen until the Sun moves to the equator, where day and night are equal. Cycle. The Antarctic region is the opposite of the North Pole.

Black, the South Pole and the North Pole both belong to the polar regions, and there are also days and nights, the day is called the polar day, and the night is called the polar night! When the sunlight shines directly south of the equator, the South Pole enters the polar day, regardless of day and night, 24 hours a day is all day, at this time the Arctic region is the polar night, and the whole day is night; When the sun shines directly on the region north of the equator, the South Pole enters the polar night, which is dark 24 hours a day, and the North Pole enters the polar day, and it is daytime all day!

Of course there are nights in Antarctica, and a night is not 12 hours, it is a long time, and the night is very cold.

There is no darkness in the Nordic summer, and it is only dark in spring and autumn. In winter, there is no daylight. It is because Northern Europe is located in the position of the Arctic continent, and the summer sun moves to the northern hemisphere, so that the Arctic has day, and Antarctica is night.

This is caused by the rotation of the earth, and it is a fact that cannot be changed, and this natural law is formed in this way in the four seasons of spring, summer, autumn and winter.

In Northern Europe, summer is not dark, but spring and autumn. There is no winter. This is because Northern Europe is in the North Pole, and in the summer the sun moves to the Northern Hemisphere, so the North Pole becomes daytime and Antarctica becomes night.

This is due to the rotation of the Earth, which is an immutable fact. This natural law is formed in spring, summer, autumn and winter.

Every year at the vernal equinox, the sun shines directly on the Earth's equator. Then the earth gradually moved, and in the summer, the sunlight came back to the northern hemisphere. Later, after the autumnal equinox, the sun will shine directly on the equator.

In winter, the sun shines directly over the Southern Hemisphere. During the summer months, the Arctic is exposed to sunlight all day long, and no matter how the Earth rotates, the North Pole does not enter the dark hemisphere of the Earth that is not exposed to sunlight, and the sun is seen hanging in the sky for months. It wasn't until after the autumnal equinox that the sun reached the southern hemisphere, and the North Pole entered the dark hemisphere of the earth, and the long night fell.

Throughout the winter, daylight does not reach the North Pole. Half a year later, it was not until the vernal equinox that the sun reappeared. So the Arctic half a year is day (from the spring equinox to the autumnal equinox) and the other half is night (from the autumnal equinox to the spring equinox).

In the same way, the Antarctic is also half a year of day and half a year of night, but the time and the North Pole are just the opposite. When the North Pole is daylight, the South Pole is night; When it's night at the Arctic, it's day at the South Pole.

The sunlight should not reach the north and south poles, so this happens.

This is due to the fact that the South Pole and the North Pole are at the poles, which leads to the phenomenon of polar day and night.

Due to the rotation of the Earth, the South Pole and the North Pole should receive different levels of sunlight, which is why polar day and night will occur.

This is the polar day and night phenomenon of the North and South Poles Polar day and night are unique natural phenomena in the polar circle, and the special natural phenomena of polar day and night are the result of the rotation of the earth along the inclined axis of the earth.

The polar day and night range and time are:The polar day and night ranges are within 66°34 north latitude of the Arctic Circle and within 66°34 minutes south latitude of the Antarctic Circle. The Antarctic polar day is from September 24 to March 20, and the polar night is from March 22 to September 22.

The Arctic Polar Day is from March 22 to September 22, and the Polar Night is from September 24 to March 20.

The principle of the production of hidden rocks during the polar day and night:

As the Earth revolves around the Sun in an elliptical orbit, it also rotates around its own inclined axis. It turns out that when the earth rotates, the earth's axis forms an approximate inclination angle with its vertical line, so that when the earth rotates, there is always one of the poles facing the sun for 6 months, and it is all daytime; The other pole is turned away from the sun, and it is all night.

The North and South Poles are amazing natural phenomena that no other continent has.

Yes. Every year in the north and south poles, "polar day" and "polar night" alternate. Six consecutive months in a year are daylight (called polar day) and six months are night (called polar night).

There is a pattern to the occurrence of polar day: the polar phenomenon occurs at the pole of the hemisphere where the sun shines directly. The polar day is related to the latitude of the direct point of the sun, and the latitude difference between its boundary and the pole is the latitude of the point of direct sunlight.

So every year after the vernal equinox, there will be a polar day near the North Pole, and then the polar day will become larger and larger, reaching its maximum on the summer solstice, and its boundary will reach the Arctic Circle. After the summer solstice, the extent of the polar day near the Arctic Circle gradually decreases, and by the autumnal equinox the polar day disappears completely.

The Antarctic continent is the most difficult continent to access. The closest continent to the Antarctic continent is South America, and between them is the 970-kilometer-wide Drake Passage. The Antarctic continent is not only far from the rest of the continent, but is also surrounded by ice shelves and ice floes of kilometers or even hundreds of kilometers, which can cover an area of up to 19 million square kilometers in winter.

Even in the summer of Antarctica, its area is 2.6 million square kilometers; There are also tens of thousands of huge icebergs floating in the oceans around the Antarctic continent, which make sea navigation extremely difficult and dangerous. Antarctic Circle: The 66 degrees 34 minutes south latitude is the Antarctic Circle.

There will be polar day and polar night phenomena in the Polar Circle, with the south of the Antarctic Circle being the southern cold zone and the north of the south temperate zone.

Because the earth is tilted and the sun shines, half of the time at the north and south poles is day or night.

For example, in summer, the North Pole is polar day, the South Pole is polar night, and in winter it is the opposite.

For details, please refer to High School Geography.

The South Pole is colder because the South Pole is a continent and the North Pole is an ocean. Under certain circumstances, there may be no night at the North and South Poles, but if there is no night at the South Pole, there will be no day at the North Pole, and vice versa.

The South Pole and the North Pole, two of the most incredible places on Earth are paranormal.

There are days and nights like us.

The Antarctic and the North Pole are an important part of the earth's non-desertification, because it can nourish the whole earth and maintain water resources.
