People use to believe the universe was centered around the Earth. BUt now with modern technology we know that it is obviously not.
In regions where the sun's rays hit at an angle, solar energy is less than the region which is exposed to direct sun rays and the climate is cold.
- here the slanting sun rays fall on the frigid zone.
- the frigid zone receives slanting ray due to The higher the latitude, the less is the angle that the sun's rays make with the surface of the earth. Hence , the polar regions ( frigid zone ) receive slanting rays of the Sun.
- on the other hand The Tropical zone gets vertical rays of the sun, while temperate and polar zones receive slanting rays of the sun.
- North and South poles get more slanted sun rays. The axis of the earth is not straight, it is tilted in the angle of approximately 23.5°.
- The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse and due to low heating the region becomes cold .
