Why does Antarctica have six months continuous sun light?

Answer 1

Both Antarctica and the Arctic have long periods of daylight followed by equally long periods of night. This is because they both lie at very high latitudes.

When the southern end of the Earth is pointing more towards the sun and giving the Southern Hemisphere its summer, the position of Antarctica means that the sun never actually sets below the horizon, but appears to circle around in the sky. No shadow is cast, which is all night actually is. At the same time, the arctic is having its long night, because the northern end is tilted so far away from the sun that the light does not reach it fully, or at all for a few weeks or months. The complete day and complete night do not last a full six months except at the absolute poles, but gradually the days lengthen a little - or shorten.

Sunsets beyond about 66 degrees S and 66 degrees N sets -- and rises -- over the course of six to eight weeks during spring and fall. Otherwise, the sun will either always be present or always be hidden.

Answer 2

Antarctica is not dark for six months. The South Pole -- 90 degrees S, however, experiences no sunrises for six months.

Antarctica is as large as USA and Mexico combined, so the duration of the period of no sunrise varies, depending on where you are on the continent. At the Antarctic Circle -- about 66 degrees S, this period is 24 hours.

Answer 3

The phenomenon you describe only occurs at the South Pole. It is caused by the Earth's tilt away from the sun.

On other locations on the continent, the period varies from six months to one day.

Answer 4

The phenomenon you describe is only true for the South Pole -- and the North Pole, in fact.

All locations south of about 66 degrees S -- the Antarctic Circle -- experience at least one 24-hour period annually of no sunrise/ sunset. The South Pole's period -- located at the extreme extent south of the Antarctic Circle -- is six months.

Other locations on the continent experience different periods: days, weeks or months.

The reason they have these long periods of daylight is that the tilt of the Earth's axis causes the pole to point towards the Sun in summer.

Answer 5

All locations on Earth beyond about 66 degrees of latitude, experience at least one 24-hour period per year of no sunrise/ sunset.

All of Antarctica lies beyond the Antarctic Circle -- 66 degrees S -- and the periods of no sunrise/ sunset vary in length depending on where you are on the continent. The most extreme location is the South Pole, where the period lasts six months.

Answer 6

Because as the Earth orbits the sun, the fact that Earth is tilted means for 6 months, Antarctica is facing away from the Sun. It is the same effect that gives seasons in other parts of the world, with days being shorter in winter.

i dont no search it up on Google noob

yes!
