Question

why temperature decreases progessively from equator towards the poles and why it is zero in polar areas and higher in high altitudes?

Answer 1

Temperature decreases progressively from equator towards the poles because the sun is less far from the equator and it receives more and direct sunlight and as we go to equator it decreases and in poles it becomes very little or none. As sunlight decreases then the temperature also decreases and it becomes zero in poles. It is higher in altitudes because sunlight is more harder in height then land.

Answer 2

Answer:

at equator, the sun rays fall perpendicular which results into the maximum amount of heat and ligth in that area, but as we move towards the pole so the surface becomes more slanted or curved due to which the sunrays and the ligth amount is less there. this is the reason or decrease in the temprature.

the sun rays which come to the surface of the earth are absorbed and radiated back by the earths surface, the effect of this heat radiation is maximum at the ground level and minimum at the altitudes. the heat radiations fail to be effective at the heights.
