(g) Why do the poles experience about six months day and six months night?  

Answer:

(g) When the rays of the sun fall directly on the Tropic of Cancer (21st June), the areas near the South Pole receive less heat. The North Pole is inclined towards the sun and places beyond the Arctic circle experience continuous daylight. At this time, the Southern Hemisphere has the opposite season. The nights are long and areas beyond Antarctic circle get continuous night. The reverse will happen on 22nd December.
