GROUP 1

Name of River:Amazon River Source of picture :www.google.com Description of River:The Amazon River of South America is the largest river in the world by volume, with a total river flow greater than the next eight largest rivers combined. The Amazon, which has the largest drainage basin in the world, accounts for approximately one fifth of the world's total river flow. During the wet season parts of the Amazon exceed 120 miles (190 km) in width. Because of its vast dimensions, it is sometimes called The River Sea. At no point is the Amazon crossed by bridges. This is not because of its huge dimensions; in fact, for most of its length, the Amazon's width is well within the capability of modern engineers to bridge. However, the bulk of the river flows through tropical rainforest, where there are few roads and even fewer cities, so there is no need for crossings.The Amazon River and Flooded Forests ecoregion contains an extremely high number of freshwater animal species, including two species of freshwater dolphins. The ecoregion is characterized by extensive forested areas that become flooded during each rainy season. These "flooded forests" in the Amazon region are the most extensive of this habitat type in the entire world. The cycle of flooding, and the annual regeneration that it produces, represent a globally outstanding ecological phenomenon. The entire Amazon basin contains the largest number of freshwater fish species in the world, estimated at more than 3,000 species. Uses 1)People use the water to wash themselves. (eg.bath). 2)The people use the river water for drinking. Problems
1)The Amazon River always have floods.
2)There are pirahans in the River when they drink the water they migth be eaten
