How are Rainforests formed / why are they where they are?
Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth’s tropical rain forests. From 40 to 75% of all species on Earth are indigenous to the rainforests.[1] It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the “jewels of the Earth”, and the “world’s largest pharmacy”, because of the large number of natural medicines discovered there.[2] Rainforests also supply 28% of the worlds oxygen,[3] processing it through photosynthesis from carbon dioxide. The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized
How are Rainforests formed / why are they where they are?Many of the world’s rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone.———— Tropical rainforests are rainforests in the tropics, found near the Equator (between the Tropic of Cancer and Tropic of Capricorn) and present in southeast Asia (Myanmar to Philippines, Indonesia, Papua New Guinea, and northeastern Australia), Sub-Saharan Africa from Cameroon to the Congo (Congo Rainforest), South America (e.g. the Amazon Rainforest), Central America (e.g. Bosawás, southern Yucatán Peninsula-El Peten-Belize-Calakmul), and on many of the Pacific Islands (such as Hawaiʻi). Tropical rainforests have been called the “Earth’s lungs,” although it is now known that rainforests contribute little net oxygen additions to the atmosphere through photosynthesis ———-Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfa
