Amazon river tributaries

Do not apply to broken or inflamed skin.

Its westernmost source is high in the Andes Mountains , within miles km of the Pacific Ocean , and its mouth is in the Atlantic Ocean , on the northeastern coast of Brazil.

However, both the length of the Amazon and its ultimate source have been subjects of debate since the midth century, and there are those who claim that the Amazon is actually longer than the Nile. See below The length of the Amazon. The Amazon River is located in the northern portion of South America , flowing from west to east.

Most researchers believe that it is at least 4, miles 6, km long. However, no definitive measure is available because no one is entirely sure where the Amazon ends and begins. Given the complexity of the river system, much of which is in remote areas, researchers have proposed several locations in Peru as its source.

The Amazon is well known for a number of reasons. It is the greatest river of South America and the largest drainage system in the world in terms of the volume of its flow and the area of its basin. While there is some debate about its length, the river is generally believed to be at least 4, miles 6, km long, which makes it the second longest river in the world after the Nile River in Africa.

The Amazon is also famous for the rainforest found along its shores. About 2, fish species have been found within the Amazon system, but many more remain unidentified. The small flesh-eating piranha generally feeds on other fish but may attack any animal or human that enters the water.

Other animals include caiman , river turtles , river dolphins , and manatees. The Amazon is also home to the semiaquatic capybara , the largest rodent in the world, and the nutria or coypu. The vast Amazon basin Amazonia , the largest lowland in Latin America , has an area of about 2.

Although considered a part of Amazonia by the Brazilian government and in popular usage, it is technically a separate system. More than two-thirds of the basin is covered by an immense rainforest, which grades into dry forest and savanna on the higher northern and southern margins and into montane forest in the Andes to the west.

Deforestation has accelerated, especially south of the Amazon River and on the piedmont outwash of the Andes, as new highways and air transport facilities have opened the basin to a tidal wave of settlers, corporations, and researchers. Significant mineral discoveries have brought further influxes of population.

The first European to explore the Amazon, in , was the Spanish soldier Francisco de Orellana , who gave the river its name after reporting pitched battles with tribes of female warriors, whom he likened to the Amazons of Greek mythology.

Although the name Amazon is conventionally employed for the entire river, in Peruvian and Brazilian nomenclature it properly is applied only to sections of it.
