Why does the Torrid Zone receive the maximum amount of heat?

Hint: Three major zones of the world on the basis of temperature - torrid zone, temperate zone and frigid zone. The five major parallel lines of latitudes decide the temperature of these three zones.

Complete answer: The earth has two points, that is, the North pole and the South pole. The imaginary circle drawn around the globe exactly halfway between the two poles is termed as the equator. This imaginary circle cuts the globe into two equal parts called the Northern hemisphere and Southern hemisphere. The parallels are circles of varying lengths. The length of the parallels decreases gradually from the equator into poles. The equator is the longest parallel. The 60 parallel is half the length of the equator and the poles are just points.
 All parallel circles from the equator up to the poles are called parallel latitudes. There are four important parallel of latitudes besides the equator (0°), the North pole (90°N) and the South pole (90°S), those are - Tropic of Cancer (23.5°North), Tropic Capricorn (23.5°South), Arctic Circle (66.5°North), and the Antarctic Circle (66.5°South).
The area between the Tropic Cancer and Tropic of Capricorn is the torrid zone. The sun faces the area between the tropics at least once a year on all latitudes. So, this zone is considered to be the hottest zone of the earth, as it receives direct rays of the sun throughout the year. It is also known as the tropical zone. About half of India lies in this zone.

Note: The torrid zone covers 39.78 percent of the Earth’s surface. This zone has a variety of topographic features, many deserts, as well as mountains, falls in this zone. The Andes Mountain Chile and Argentina lie in this tropical zone.
