The Amazon rainforest[a] also known in English as Amazonia or the Amazon Jungleis a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This region includes territory belonging to nine nations. Four nations have " Amazonas " as the name of one of their first-level administrative regions and France uses the name " Guiana Amazonian Park " for its rainforest protected area.

The Amazon represents over half of the planet's remaining rainforests, [1] and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated billion individual trees divided into 16, species.

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, amazon rainforest homework help, as was their custom. Tribal societies are well capable of escalation to all-out wars between tribes. Thus, in the Amazonas, there was perpetual animosity between the neighboring tribes of the Jivaro. Several tribes of the Jivaroan group, including the Shuarpractised headhunting for trophies and headshrinking.

More than a third of the Yanomamo males, on average, died from warfare. During the Amazon rubber boom it is estimated that diseases brought by immigrants, amazon rainforest homework help, such as typhus and malariakilled 40, native Amazonians. Nine countries share the Amazon basin—most of the rainforest, The other eight countries include Peru with The rainforest likely formed during the Eocene era from 56 million years to 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.

The rainforest has been in existence for at least 55 million years, and most of the region remained free of savanna -type biomes at least until the current ice age when the climate was drier and savanna more widespread. Following the Cretaceous—Paleogene extinction eventthe extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent. Climate fluctuations during the last 34 million years have allowed savanna regions to expand into the tropics.

During the Oligocenefor example, the rainforest spanned a relatively narrow band. It expanded again during the Middle Miocenethen retracted to a mostly inland formation at the last glacial maximum. During the mid-Eoceneit is believed that the drainage basin of the Amazon was split along the middle of the continent by the Purus Arch. Water on the eastern side flowed toward the Atlantic, while to the west water flowed toward the Pacific across the Amazonas Basin.

Within the last 5—10 million years, this accumulating water broke through the Purus Arch, amazon rainforest homework help, joining the easterly flow toward the Atlantic.

There is evidence that there have been significant changes in the Amazon rainforest vegetation over the last 21, years through the last glacial maximum LGM and subsequent deglaciation.

Analyses of sediment deposits from Amazon basin paleolakes and the Amazon Fan indicate that rainfall amazon rainforest homework help the basin during the LGM was lower than for the present, and this was almost certainly associated with reduced moist tropical vegetation cover in the basin.

Some scientists argue that the rainforest was reduced to small, isolated refugia separated by open forest and grassland; [15] other scientists argue that the rainforest remained largely intact but extended less far to the north, south, and east than is seen today, amazon rainforest homework help.

The dust contains phosphorusimportant for plant growth. The yearly Sahara dust replaces the equivalent amount of phosphorus washed away yearly in Amazon soil from rains and floods. CALIPSO has measured variations in the dust amounts transported — an 86 percent drop between the highest amount of dust transported in and the lowest in amazon rainforest homework help A possibility causing the variation is the Sahela 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.

Amazon phosphorus amazon rainforest homework help comes as smoke due to biomass burning in Africa. Based on archaeological evidence from an excavation at Caverna da Pedra Pintadahuman inhabitants first settled in the Amazon region at least 11, years ago. For a long time, it was thought that the Amazon rainforest was only ever sparsely populated, as it was impossible to sustain a large population through agriculture given the poor soil.

Archeologist Betty Meggers was a prominent proponent of this idea, as described in her book Amazonia: Man and Culture in a Counterfeit Paradise. She claimed that a population density of 0. It is believed that civilization was later devastated by the spread of diseases from Europe, such as smallpox.

Since the s, numerous geoglyphs have been discovered on deforested land dating between AD 1—, furthering claims about Pre-Columbian civilizations.

The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed.

Among those were evidence of roads, bridges and large plazas. On 3 SeptemberVarig Flight crashed into the Amazon, killing 13 out of the 54 people on board. The Legacy jet landed safely, but flight lost control, broke up in mid-air, amazon rainforest homework help crashed into the Amazon, killing all people on board. There have been 72, fires in Brazil inwith more than half within the Amazon region.

Wet tropical forests are the most species-rich biomeand tropical forests in the Americas are consistently more species rich than the wet forests in Africa and Asia. One in ten known species in the world lives in the Amazon rainforest. The region is home to about 2. To date, at least 40, plant species, amazon rainforest homework help, 2, fishes[43] 1, birds, mammals, amphibians, and reptiles have been scientifically classified in the region.

Scientists have described between 96, andinvertebrate species in Brazil alone. The biodiversity of plant species is the highest on Earth with one amazon rainforest homework help finding a quarter square kilometer 62 acres of Ecuadorian rainforest supports more than 1, tree species. Leaves expand during the dry season when sunlight is at a maximum, then undergo abscission in the cloudy wet season. These changes provide a balance of carbon between photosynthesis and respiration.

The rainforest contains several species that can pose a hazard. Among the largest predatory creatures are the black caimanjaguarcougarand anaconda. In the river, electric eels can produce an electric shock that can stun or kill, while piranha are known to bite and injure humans. There are also numerous parasites and disease vectors.

Vampire bats dwell in the rainforest and can spread the rabies virus, amazon rainforest homework help. Bullet ants have an extremely painful sting.

Parrots at clay lick in Yasuni National Parkamazon rainforest homework help, Ecuador. Deforestation is the conversion of forested areas to non-forested areas. The main sources of deforestation in the Amazon are human settlement and development of the land.

Prior to the early s, access to the forest's interior was highly restricted, and the forest remained basically intact. However, the colonists were unable to manage their fields and the crops because of the loss of soil fertility and weed invasion, amazon rainforest homework help. In the s, construction began on the Trans-Amazonian highway. This highway represented a major threat to the Amazon rainforest. New research however, conducted by Leydimere Oliveira et al.

So despite the popular perception, there has been no economical advantage for Brazil from logging rainforest zones and converting these to pastoral fields.

The needs of soy farmers have been used to justify many of the controversial transportation projects that are currently developing in the Amazon. The first two highways successfully opened up the rainforest and led to increased settlement and deforestation. Since the discovery of fossil fuel reservoirs in the Amazon rainforest, oil drilling activity has steadily increased, peaking in the Western Amazon in the s and ushering another drilling boom in the s.

The European Union—Mercosur free trade agreementwhich would form one of the world's largest free trade areas, has been denounced by environmental activists and indigenous rights campaigners.

The transformation from forest to farm is evident by the paler square shaped areas under development. Environmentalists are concerned about loss of biodiversity that will result from destruction of the forestand also about the release of the carbon contained within the vegetation, which could accelerate global warming.

One computer model of future climate change caused by greenhouse gas emissions shows that the Amazon rainforest could become unsustainable under conditions of severely reduced rainfall and increased temperatures, amazon rainforest homework help, leading to an almost complete loss of rainforest cover in the basin by Inenvironmentalist C. Peters and two colleagues stated there is economic as well as biological incentive to protecting the rainforest.

As indigenous territories continue to be destroyed by deforestation and ecocidesuch as in the Peruvian Amazon [75] indigenous peoples ' rainforest communities continue amazon rainforest homework help disappear, while others, like the Urarina continue to struggle to fight for their cultural survival and the fate of their forested territories. Meanwhile, the relationship between non-human primates in the subsistence and symbolism of indigenous lowland South American peoples has gained increased attention, as have ethno-biology and community-based conservation efforts.

About 1, square kilometres , acres have been put onto some sort of conservation, which adds up to a current amount of 1, square kilometres , acres. In Aprilthe Ecuadorian court stopped oil exploration activities in 1, square kilometers of the Amazon rainforest. In Julythe Ecuadorian court forbade the government to sell territory with forests to oil companies.

Aerosols over the Amazon each September for four burning seasons through The aerosol scale yellow to dark reddish-brown indicates the relative amount of particles that absorb sunlight. Deforestation in the Amazon rainforest region has a negative impact on local climate, amazon rainforest homework help.

It was one of the main causes of the severe drought of — in Brazil. Half of the rainfall in the Amazon area is produced by the forests. The use of remotely sensed data is dramatically improving conservationists' knowledge of the Amazon basin.

Given the objectivity and lowered costs of satellite-based land cover analysis, it appears likely that remote sensing amazon rainforest homework help will be an integral part of assessing the extent and damage of deforestation in the basin. The use of remote sensing for the conservation of the Amazon is also being used by the indigenous tribes of the basin to protect their tribal lands from commercial interests.

Using handheld GPS devices and programs like Google Earthmembers of the Trio Tribe, who live in the rainforests of southern Suriname, map out their amazon rainforest homework help lands to help strengthen their territorial claims.

To accurately map the Amazon's biomass and subsequent carbon related emissions, the classification of tree growth stages within different parts of the forest is crucial. InTatiana Kuplich organized the trees of the Amazon into four categories: mature forest, regenerating forest [less than three years], regenerating forest [between three and five years of regrowth], and regenerating forest [eleven to eighteen years of continued development]. Inparts of the Amazon basin experienced the worst drought in one hundred years, [87] and there were indications that may have been a second successive year of drought.

According to the World Wide Fund for Naturethe combination of climate change and deforestation increases the drying effect of dead trees that fuels forest fires. Inthe Amazon rainforest experienced another amazon rainforest homework help drought, in some ways more extreme than the drought.

The drought had three epicenters where vegetation died off, whereas inthe drought was focused on the southwestern part, amazon rainforest homework help. The findings were published in the journal Science, amazon rainforest homework help. In a typical year, the Amazon absorbs 1.

In Brazil's protections of the Amazon rainforest were slashed, resulting in a severe loss of trees.
