प्रश्न
Give reasons for the following
Vertical rays are hotter than slanting rays.

Vertical rays are hotter, because these cross shorter distance from the sun to the earth. Consequently the tropical belt is hotter than temperate and polar areas.
उत्तर २
Vertical rays remain focussed over a shorter area than slanting rays. During slanting rays solar radiation is spread over a larger area.
