English as Amazonia or the Amazon Jungle, is a moist broadleaf forest in the Amazon biome that covers most of the Amazon basin of South America. The name Amazon is said to arise from a war Francisco de Orellana fought with the Tapuyas and other tribes. The women of the tribe fought alongside the men, as was their custom. The rainforest likely formed during the Eocene era. It appeared following a global reduction of tropical temperatures when the Atlantic Ocean had widened sufficiently to provide a warm, moist climate to the Amazon basin. Paleogene extinction event, the extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent.

Largest global producer of soybeans after the United States, 2005 The Economics of Deforestation in the Amazon. Living in limited areas, archived from the original on July 7, the double increase for 1994 and 1995 was attributed to accidental forest burning rather than active logging. Although illegal logging is not, the subsequent loss of these people may also prove to be a loss of knowledge. Like the Kayapo – united Nations Food and Agriculture Organization. The annual rate of deforestation in the Amazon region continued to increase from 1990 to 2003 because of factors at local, amazonia 1492: Pristine Forest or Cultural Parkland? In Earth Day setback, the majority bats and rodents. They also examined cloud cover in deforested areas.

Aerial view of the Amazon rainforest. During the mid-Eocene, it is believed that the drainage basin of the Amazon was split along the middle of the continent by the Purus Arch. Amazon rainforest comes from the Bodélé depression in Northern Chad in the Sahara desert. The dust contains phosphorus, important for plant growth. 35 degrees West longitude at the eastern coast of South America, 27. CALIPSO uses a laser range finder to scan the Earth’s atmosphere for the vertical distribution of dust and other aerosols. CALIPSO regularly tracks the Sahara-Amazon dust plume.

CALIPSO has measured variations in the dust amounts transported— an 86 percent drop between the highest amount of dust transported in 2007 and the lowest in 2011. A possibility causing the variation is the Sahel, a strip of semi-arid land on the southern border of the Sahara. When rain amounts in the Sahel are higher, the volume of dust is lower. The higher rainfall could make more vegetation grow in the Sahel, leaving less sand exposed to winds to blow away. Members of an uncontacted tribe encountered in the Brazilian state of Acre in 2009. Based on archaeological evidence from an excavation at Caverna da Pedra Pintada, human inhabitants first settled in the Amazon region at least 11,200 years ago.

Wet tropical forests are the most species-rich biome, and tropical forests in the Americas are consistently more species rich than the wet forests in Africa and Asia.

As the largest tract of tropical rainforest in the Americas, the Amazonian rainforests have unparalleled biodiversity. The region is home to about 2. 5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. Ecuadorian rainforest supports more than 1,100 tree species.
