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.
