Rainforests are wooded areas distinguished by high precipitation, with yearly rainfall that ranges from 250 cm to 450 cm (98 inches to 177 inches). Rainforests are of two types, such as temperate rainforests and tropical rainforests. The monsoon drain, which is otherwise called as the inter-tropical convergence region, plays a vital role in making the climatic conditions essential for the tropical rainforests of the earth.
Approximately 40 percent to 75 percent of all biotic species are native to the rainforests. It has been projected that there may be several millions of genus of plants, microorganisms and insects still not found in tropical rainforests. These rainforests have been named the "world's largest pharmacy", and the "jewels of the Earth", as more than one fourth of natural medicines have been found there. Rainforests are as well, accounting for 28 percent of the oxygen yield of the world, occasionally misnamed oxygen manufacture, processing it during photosynthesis from carbon dioxide and consuming it during respiration.
The bushes in some regions of a rainforest can be limited by poor diffusion of sunshine to ground level. If the leaf cover is thinned or destroyed, the underground is quickly colonized by a thick, knotted growth of shrubs, vines, and small trees, known as a jungle. The word jungle is as well, occasionally applied to tropical rainforests in general.
Tropical rainforests are distinguished by a wet and warm type of weather. Average monthly temperatures during all months of the year will go beyond 64 F (18 C). Mean yearly rainfall will not be less than 168 cm (66 inches) and will go beyond 1,000 cm (390 inches) even though it usually lies between 175 cm (69 inches) and 200 cm (79 inches). Most of the rainforests of the world are linked with the setting of the monsoon channel. Tropical rainforests are situated in the tropics, that is, in the equatorial region between the Tropic of Capricorn and the Tropic of Cancer.
Tropical rainforests are found in the southeastern part of Asia, ranging from Burma to Sri Lanka, Malaysia, Philippines, Indonesia, northeastern parts of Australia and Papua New Guinea. They are also found in sub-Saharan Africa, extending from Cameroon to the Congo Rainforest. The Amazon Rainforest can be found in South America, Bosawas in Central America and on several of the Pacific Islands, like Hawaii. Tropical rainforests have been named as the "Earth's lungs", even though it is currently recognized that rainforests deliver little net oxygen to the atmosphere during photosynthesis.
Tropical forests envelop a huge part of the world, but temperate rainforests crop up only in only some areas around the globe. Temperate rainforests are a kind of rainforests that can be found in temperate regions. They can be found in North America, such as in the Pacific Northwestern region in Alaska, Washington, British Columbia, California and Oregon. In Europe, they can be found in parts of the British Isles, like the coastal regions of Scotland and Ireland, in the southern parts of Norway, in the western regions of Balkans along the Adriatic coastline, including in Galicia and coastal regions of the eastern shores of the Black Sea, including coastal Turkey and Georgia.
