The tropical zone is found around the Earth's equator, extending approximately between 23.5° north latitude (the Tropic of Cancer) and 23.5° south latitude (the Tropic of Capricorn). This region is characterized by the sun being directly overhead at least once a year, resulting in generally hot and humid weather with little seasonal temperature variation
. This belt-shaped region covers about 40% of the Earth's surface and includes many countries in South America, Africa, Asia, and Oceania. Tropical countries within this zone experience climates typically marked by consistently high temperatures (average monthly temperatures above 18°C or 64.4°F) and distinct wet and dry seasons
. In summary, the tropical zone is the area between the Tropic of Cancer and the Tropic of Capricorn, centered on the equator, where the sun can be directly overhead and the climate remains warm year-round
