What is the soil in the Amazon rainforest like?
Soil in the tropical rainforest's is very nutrient poor. The topsoil is only one to two inches (2.5 to 5 centimeters) deep. The only reason plant life is so lush is because the plants store the nutrients in themselves rather than getting them from the soil. When plants decay, other growing plants tap the nutrients from the dead matter and reuse nutrients left over from that plant. This is why farmers can only use the rainforest's soil for one or two years after they clear cut it, before all nutrients are stripped from the soil.The reason the soil so infertile is because it is more than 100 million years old, and has taken a beating from the elements. After time, rain washes minerals out of the soil, leaving it more acidic and nutrient poor. Soil exposed to the heat and condensed sunlight turns it into red clay. Other soils just cannot deal with minerals, and turn it into compounds useless to plants. There are some fertile patches of soil in the rainforest's, but they are scattered throughout the thick vegetation.
How does the Amazon rainforest help us?
The amazon rainforest hold 70% of the world plants that have anticancer properties witch means if you have cancer the cure you could get would possibly be from the rainforest .
Also lots of tribes - that have never had contact with the outside world live there and animals-that can only survive in the rainforest!

Yes, the land is flat in the amazon Rainforest. There are hardly any hills and it is low lying land. The land is covered by plants and is home to insects and small mammals. The vegetation hardly gets any sunshine on ground level.
What is in the Amazon rainforest?
A rain forest is simply a forest that has lots and lots of rain each year (+70in a year) The Amazon rain forest in particular is very large it covers a good portion of South America (1.4 billion acres). It calls 9 different countries home and is home to thousands of types of trees and animals. The climate is warm (about 79* F) and humid.

How big is the Amazon rainforest compared to Wales?
The area, also known as Amazonia or the Amazon Basin encompasses seven million kilometers (1.2 billion acres), though the forest itself occupies some 5.5 million kilometers, located within eight nations: Brazil (with 60 percent of the rainforest), Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana.
Amazon Rainforest is also known as the Amazon Basin. Amazon constitutes half of the total rainforest of the earth. It occupies the northern part of the South America. It constitutes eight nations, some of which includes Brazil, Peru, Ecuador and other neighbouring nations. It has a total area which extends more than 1.6 million sq miles.
How many animals in amazon rainforest?
Countless. Literally. There are still species in there that mankind hasn't discovered yet. However, due to the fact that it's being cut down at a rapid pace, the animal count is decreasing. On the contrary, there are still many animals - more than we can imagine.
What are the three tribes in the amazon rainforest?
In northwest of the Amazon rainforest in areas located in Brazil, Colombia and Venezuela the tribes that are found are: Baniwa, Kuripako, Dow, Hupda, Nadöb, Yuhupde, Baré, Warekena, Arapaso, Bará, Barasana, Desana, Karapanã, Kubeo, Makuna, Mirity-tapuya, Pira-tapuya, Siriano, Tariana, Tukano, Tuyuca, Wanana, Tatuyo, Taiwano, Yuruti, Kakwa and Nukak.
In the Alto Xingu region in the Brazilian state of Mato Grosso the tribes that are found are: Aweti, Kalapalo, Kamaiurá , Kuikuro, Matipu, Mehinako, Nahukuá, Trumai, Wauja, Yawalapiti, Ikpeng, Kaiabi, Suyá and Yudja.
the rain forests are hard and grueling especially in summer when it reaches up to 40 degrees Celsius.
It also is hard because the animals in the rain forest lose their homes each and every day.

What is the conflict in the Amazon Rainforest?
The Native Amazonians came to the Rainforest over 12,000 years ago. They believe the land that they arrived at first, is rightfully theirs. It has now more rapidly become hard for the Natives to continue there way of live because of the recent "modifications" of the rainforests. The rainforest first started being deforested when the capital of Brazil changed from he coastal city of Rio de Janeiro to Brasilia. Brazil's government made the decision to change the capital more inland for easier access. In the proccess of relocating, the rainforest had to be cut down to create space for the new city that would soon become very populated. As well as deforestation for land development, it is the job of loggers to cut down trees to use for products. Although there have been many reserved areas of the rainforest, the destruction is still a great problem. The government and Natives have trouble coming to agreements over the land.

The Amazon rainforest, also known as Amazonia, is one of the world's greatest natural resources. Because its vegetation continuously recycles carbon dioxide into oxygen, it has been described as the "Lungs of our Planet". About 20% of earth's oxygen is produced by the Amazon rainforest.
The Amazon rainforest gets its name from the Amazon River, the life force of the rainforest. The Amazon River begins in the Peruvian Andes, and winds its way east over the northern half of South America. It meets the Atlantic Ocean at Belem, Brazil. The main river is about 4,080 miles long. Its drainage basin covers 2,722,000 million square miles, and lies in the countries of Brazil, Columbia, Peru, Venezuela, Ecuador, Bolivia, and the three Guyanas. Sixteen percent of all the world's river water flows through the Amazon delta. Twenty eight billion gallons of water flow into the Atlantic every minute, diluting the salinity of the ocean for more than 100 miles offshore. The Amazon rainforest watershed is home to the world's highest level of biodiversity.
Amazonia receives about 9 feet of rain every year. Fifty percent of this returns to the atmosphere through the foliage of trees. Most of the Amazon River's water comes from the annual snowmelt high in the Peruvian Andes. Between June and October, the water level rises by 30 to 45 feet. Tens of millions of acres of rainforest are covered by water as the flood advances, reaching as far inland from the main channel as 12 miles.
Some 15 million years ago, the Amazon River flowed westward into the Pacific Ocean. When the South American plate moved into another tectonic plate, the Andes Mountains slowly rose up and blocked the flow of the river. As the river system backed up, freshwater lakes were formed, and the environment of the Amazon basin changed drastically. Then about 10 million years ago the river found its way eastward towards the Atlantic.
The Amazon rainforest is the drainage basin for the Amazon River and its many tributaries. The northern half of the South American continent is shaped like a shallow dish. About 1,100 tributaries, seventeen of which are over 1,000 miles long, drain into this depression. Whenever rain falls in the river basin, it all drains into Amazon rainforest and into the Amazon River. The Amazon is the largest river system in the world. At some points, the Amazon River is one mile wide, while at other points it can be thirty-five miles wide. At Belem, where the river flows into the Atlantic Ocean, it can be 200 to 300 miles across, depending on the season. Some of the animals that make their home here are river otters, freshwater river dolphins, turtles, piranha, manatees, electric eels, and a remarkable, giant air-breathing fish called the piraracu.
The world's largest tropical rainforest, Amazonia covers more than half of Brazil. The canopy of Amazonia is less studied than the ocean floor. Scientists believe that the canopy may contain half of the world's species. Over 500 mammals, 175 lizards and over 300 other reptiles species, and one third of the world's birds live in Amazonia. It is estimated that about 30 million insect types can be found here. Competition for survival is fierce. This may explain why over millions of years of evolution so many highly adapted species have evolved in the canopy of Amazonia. The most intense competition is between animals and plants. Both plants and animals have made adaptations to defend themselves from being eaten, and to overcome these defensive systems. Plants trap sunlight and turn it into energy for themselves and the herbivores of the canopy.
Some animals found in the canopy are the harpy eagle, which preys on monkeys, kinkajous, sloth, reptiles, and other birds. Sloths spend most of their lives in the treetops. Their diet of low nutrition leaves forces them to conserve energy, causing the sloth to spend 80% of its life resting. A large portion of a howler monkey's diet consists of leaves, which are hard to digest. Their metabolism is so low that they need to warm themselves up in the sunlight after a chilly night. Leaf-cutter ants are responsible for harvesting a sixth of the area's leaves, bringing leaf fragments to their underground nests. They play a critical role in the rainforest's ecosystem by pruning the vegetation, which stimulates new growth, and breaking down the leaves to renew the soil.
The Amazon rainforest consists of four layers or communities. Each layer has unique ecosystems, plants, and animals adapted to that system. The emergent layer is the tallest layer, where trees can be as tall as 200 feet, and rise well above the canopy. Here they are exposed to fluctuation of temperature, wind, and rainfall. The leaves are small and covered with a thick waxy surface to hold water. They take advantage of the wind by developing winged seeds that are blown to other parts of the forest. Trunks can be up to 16 feet around and braced by massive buttress roots. Some of the animals find everything they need to survive in the emergent layer and never leave it.
The main layer of the rainforest is the canopy. Most canopy trees have smooth, oval leaves that come to a point, known as a drip tip. This allows water to flow off the leaf quickly and prevents the growth of fungi, mosses, and lichens. The canopy's leaves are very dense and filter out about 80% of the sunlight. Many flowers and fruits grow in this layer. Epiphytes cover every available surface and bromeliads provide drinking water for the many canopy creatures, and breeding pools for tree frogs.
The understory only gets about two to five percent of the available sunlight. The plants find unique ways to adapt to this shadowy existence. Their solar-collecting leaves grow large, and are dark green in color. They don't often grow more than 12 feet in height. Because there is very little air movement, they rely on insects and animals to pollinate their flowers. Some grow large flowers and fruits low on their trunks to allow larger, non-climbing animals to eat and disperse their fruit. The largest concentrations of insects inhabit this layer.
The forest floor is the lowest layer and almost no plants grow here. Only about 2% of the sunlight filters through. The floor is littered with decomposing vegetation and organisms that are broken down into usable nutrients. Many nutrients are locked into this biomass. Tree roots stay close to the surface to access these nutrients. Large animals forage for roots and tubers, while insects like millipedes, scorpions, and earthworms use the litter as a source of food.
Despite all of its abundant richness, Amazonia's giant trees grow in the poorest of soil. The top two inches of the acidic soil contains 99% of the nutrients. Nine tenths of the forest's energy is stored in the leaves and tissues of the trees themselves. The forest floor is a porous mass that prevents minerals and nutrients from being washed away and lost. As soon as a tree falls, or a creature dies, decomposers begin to turn it into a food source and mulch. The vegetation to renew the cycle quickly absorbs the nutrients that are released. This is the tightest, most efficient ecosystem in nature. The destruction of one part of the system can spell the destruction of the whole system.
High temperatures and the amount of rain are the same throughout the year in Amazonia. The climate is warm and humid, with average temperatures around 79° F. The difference between day and night time temperatures is greater than those between seasons.
Today, more than 20% of the Amazon rainforest has been destroyed and is gone forever. The land is being cleared for cattle ranches, mining operations, logging, and subsistence agriculture. Some forests are being burned to make charcoal to power industrial plants. More than half of the world's rainforests have been destroyed by fire and logging in the last 50 years. Over 200,000 acres are burned every day around the world, or over 150 acres every minute. Experts also estimate that 130 species of plants, animals, and insects are lost every day. At the current rate of destruction, it is estimated that the last remaining rainforests could be destroyed in less than 40 years.
Native peoples of the Amazon rainforest have used different plants for centuries as cures and potions for their health and survival. Scientists are now discovering that many of the plants are sources for new drugs for AIDS, cancer, diabetes, arthritis, and Alzheimer's. Quinine, muscle relaxants, steroids, and caner drugs have already been discovered. Today 121 prescription drugs sold around the world come from plant-derived sources. Although 25% of all drugs are derived from rainforest ingredients, scientists have tested only 1% of tropical plants.
Another concern for Amazonia is the fate of it indigenous people. An estimated 10 million Indians were living in Amazonia about five hundred years ago. Today there are less than 200,000 indigenous peoples left in Amazonia. More than 90 tribes have been destroyed since the 1900's. Most of the shamans and medicine men remaining are 70 years old or more. With them goes a wealth of knowledge of medicinal species of plants and organisms.
