How does Earth's temperature vary in Earth's temperature zones?

Answer 1

The earth is tilted at an angle of 66.5 degrees. So, not all surfaces of the Earth receive the direct rays of the sun throughout the year. The equatorial region (23.5 degrees North to 23.5 degrees South), receive the direct rays of the sun and remain warm throughout the year as it is concentrated over a smaller area of land.

As we move further away from the Equatorial region to the temperate zones (23.5 degrees to 66.5 degrees north and south), the rays coming to the Earth are more slanting and spread over a larger area of land so the heat is concentrated over a large area making it relatively cooler.

The Polar Region (66.5 degrees to 90 degrees North and South) receive very little sunshine and remain bitterly cold for nearly 6 months of the year.

On this basis the Earth is divided into 3 climatic zones- Equatorial (Torrid), Temperate and Polar Zones.

Answer 2

Earth's temperature varies in its temperature zones due to factors like sunlight intensity and angle of incidence. The equatorial zone generally experiences higher temperatures as it receives direct sunlight more consistently. The polar zones have lower temperatures because sunlight is more spread out and at a lower angle, leading to colder conditions. The temperate zones fall in between, experiencing moderate temperatures due to varying sunlight exposure throughout the year.
