Answer 2

Answer:

The reason for this is the tilt of the earth axis.

Explanation:

Sun is visible for more than 24 hours during dakshinayan in the region between an antarctic circle and south pole because Dakshinyan is between Winter Solstice and Summer Solstice.  The South Pole faces toward the sun during the second half of this cycle because of this the Sun does not set for observers at the South Pole. At the South pole, sun shines or can say the period of daylight is 6 months long. On the Antarctic circle, they have one entire day without a sunset. The reason for this is the tilt of the earth axis.
