Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. Most tropical rainforests fall between the Tropic of Cancer and the Tropic of Capricorn.These areas receive more sunlight and the amount of sunlight and intensity of the sunlight the tropics receive doesn't vary much in comparison to other parts of the globe. The high temperatures means that evaporation happens at a fast rate, resulting in frequent rainfall.
