In other words equator has its position in the middle of the Torrid Zone and this divided the Torrid Zone into two parts and expanded in north and south upto 23 V20 N & 23 V20 S. Tropic of Cancer: The Tropic of cancer line lies on 23 V20 N in the northern hemisphere. This area is expanded upto 66 V20 N. This area indicates about moderate temperature. Tropic of Capricorn: It is the parallel of 23 V20 S in the southern hemisphere. Arctic Circle: It lies at 66 V20 north of the equator.
