This is only true at the South Pole -- 90 degrees South Latitude.

It is true because of the earth's tilt on its axis, and because of the seasonal rotation of the earth relative to the sun.

In other locations on the Antarctic continent, there is more than one sunrise and sunset. All over the continent there is some period of total sunlight (no sunsets) and total darkness (no sunrises), and the periods vary depending on the latitude.

For example, at 77 degrees South Latitude, these periods last about four months.

South of the Antarctic Circle, by definition, the earth experiences at least one day of no sunrise and no sunset.

Antarctica covers 10% of the earth's surface, and the period of no sunrise/ sunset varies depending on where you are on the continent.

Everywhere south of the Antarctic Circle -- As of 22 January 2015, it runs 66°33'45.6" south of the Equator -- there is at least one 24-hour period with no sunrise/ sunset.

At the South Pole -- 90° S -- the sun rises and sets once per year giving that geography six months of no sunset and six months of no sunrise..

It has to be about 30 degrees to snow and Antarctica can go as low as 50 below 0. So it's too cold for snow. The snow would freeze and turn to hail, ice, you name it.

Hope this helps you,

because the average temperature in Antarctica is cold enough so that almost all the snow does not melt. Also because Antarctica usually does not receive a lot of sunlight.
It is very, very cold in the Antarctic. Melting only occurs when it's above the freeIng ( or melting) point.

It is so cold because it is not facing the sun that much. The sun's rays have to travel further to reach the poles, and some heat is lost.

Where does the sun appear south of the Antarctic Circle?

It appears in the northern sky moving from east to west, right to left, except when it fails to rise for a period in the winter. Near the antarctic circle this period is only a week or two, and it is longer at places further south, until at the pole it vanishes for almost six months.

Where does the sun never rise during the winter?

Around the Earth's poles there is a region called the Arctic or the Antarctic where there is a period of weeks or months during which the Sun never rises. At places just beyond the Arctic and Antarctic circles the period is quite short, for example six weeks at Harstad, Norway which is 200km north of the Arcric circle. Near the poles the period is nearer six months.
