प्रश्न
Why is noon hotter than morning and evening?
Or
Maximum temperatures are found in the afternoon. Why?
उत्तर
The sun is overhead at noon. The Sun rays are almost vertical. But in the morning and evening, the angle of sun rays is oblique. Slanting rays fall in the morning and evening. Vertical rays are hotter than slanting rays. As the vertical rays give more heat per unit area, the noon is hotter than morning and evening.
