Why do the Poles experience about six months day and six months night?
The Poles experience six month's day and six months' night because of the following reasons:
- When the Northern hemisphere is tilted towards the Sun, the North Pole remains in the light for the whole of the day (24 hours). This position remains for six months (from 21st March to 23rd September).
- On the contrary, in the Southern hemisphere, the South Pole does not get light during these six months. Hence it experiences night for six months.
- When the Southern hemisphere is tilted towards the sun, the South Pole remains in light for 24 hours for six months from 23rd Septemeber to 21st March. Reverse are the conditions at the North Pole - six months' night.
