f) Equinox falls on 21st March and 23rd September. Why does the Southern Hemisphere experience Winter and Summer Solstice in different times than that of the Northern Hemisphere? Answer: This happens because of the angle between earth's axis and its orbit. On 21st June, the sunlight falls directly on the Tropic of Cancer.
g) The poles experience about six months of day and six months of night due to the tilt of the earth on its axis. Because of this tilt, each pole is tilted towards and away from the sun for about six months each.
