During _____________ maximum Insolation is received at the North and the South Poles.
Answers
atmosphere
Earth's current orbit
The Earth is tilted at an angle of 23.5° relative to the sun and this has a marked impact upon the amount of Insolation received by different places and at different times of the year. On December the 21st (Mr Gs birthday!) the North Pole is tilted away from the sun, and the maximum overhead sun is located at the Tropic of Capricorn. Hence the North Pole receives no insolation at this time and the Tropic of Capricorn its maximum amount. 3 months later, the Earth has moved into a position where the maximum overhead sun is over the Equator, which receives the most insolation. The Northern and Southern hemispheres are in spring and autumn respectively. On June the 21st, the Earth has continued its journey so that the maximum overhead sun is over the Tropic of Cancer (23.5° N)
