answer 31- heterosphere is the layer ofthe atmosphere in which gases Poor Mixed because of influence of the gravity which cause different weight separate into layer (option D)

answer 32- 1372 watt per square meter refers to option A amount of the energy by the atmosphere

answer 33- the criteria for the classification of the atmosphere are option D structure , compostion and function

answer 36- the unven distribution of insolation by latitude is the result of option C Earth's sphercity which present varied angle to parallel solar rays

answer 37- On earth sun passes directly overheaded at 25 degree north latitude (option B ) 1 or 365 days times a year .

answer 38- life is possible on earth because option C ozonosphere and ionosphere shields the earth surface from the ultravoilet radiation

answer 39- at all times during a year the circle of illumination option A divides earth between equal halves of lightness and darkness

answer 40- option B the sub polar point is the location on the surface of earth that receives insolation when the sun is directly overheaded.
