Sunlight strikes the tropics almost straight on, producing intense solar energy that keeps temperatures high, between 21° and 30°C (70° and 85°F). High temperatures keep the air warm and wet, with an average humidity of between 77% and 88%.
In the rainforest, trees grow to gigantic size, supported by strong, strut-like buttresses at the base of the trunk that help to stabilize them in shallow forest soils. They are home to colorful birds and a huge variety of fascinating mammals. About 80% of the world's documented species can be found in tropical rainforests, even though they cover only about 6% of the Earth's land surface.
Tropical rainforests are so warm and moist that they produce as much as 75% of their own rain through evaporation and transpiration. Such ample sunlight and moisture are the essential building blocks for tropical rainforests’ diverse flora and fauna.
The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers where the top layer or canopy contains giant trees that grow to heights of 75 m (about 250 ft) or mor
The largest rainforests are in Brazil (South America), Zaire (Africa) and Indonesia (South East Asia). Other tropical rainforest places are in Hawaii and the islands of the Pacific & Caribbean.
