The Tropic of Cancer (23 1/2° N) 3. The Tropic of Capricorn (23 1/2° S) 4.

Torrid Zone - Torrid means hot. This area is between Tropic of Cancer and Tropic of Capricorn. Therefore this area receives maximum heat of Sun and called the Torrid Zone. The mid-day sun is exactly overhead at least once a year on all latitudes . 2. Temperate Zones – Temperate means moderate. There are two Temperate Zone present on the Earth surface . (i) Northern hemisphere’s Temperate Zone - This area is present between Tropic of Cancer (23 1/2° N) and Arctic Circle (66 1/2° N). (ii) Southern hemisphere’s Temperate Zone - Thi
