उत्तर
In summer, the Sun is overhead at the Tropic of Cancer (23 1 /2° N). The northern hemisphere is inclined towards the Sun. The circle of light does not pass through the poles. The circle, of light cuts all the parallels unequally. The larger part of each parallel is in light. So days are longer than nights. At 66 1 /2° N latitude, there is 24 hour complete, continuous daylight. Thus, North pole has daylight for six months
