The Amazon, the mighty river that originates in the highlands of Peru, and along the South American continent with a long (according to the latest measurements) of 7.020 kilometers, and is the longest river in the world, runs well Peru, Colombia and Brazil. It runs through the continent from west to east. the Amazon basin is also the largest river basin in the planet's surface, which practically sustains the Amazon rainforest.

Amazon River Tour through South America
Origin of the word Amazon:
Amazon's voice comes from the Amazon River , given the Marañón by Francisco de Orellana after facing a local ethnic group in which men and women are equally defended. Orellana derived the name from the Greek myth of the Amazon warriors of Asia and Africa, narrated by Herodotus and Diodorus.
Before the Conquest, the river was not a unique name, on the contrary, Indians appointed either to the different sections with voices like Paranaguazú (Grand Pariente del Mar), Guyerma, Solimões, etc. In 1500, Vicente Yanez Pinzon, captain of a English exploration expedition, became the first European to venture into the river after discovering that its waters were navigable and drinkable. Pinzón called the river watercourse Santa Maria de la Mar Dulce, which was eventually abbreviated to Mar Dulce (the name also occurred in those times the Rio de la Plata). For some years subsequent to 1502 is also known as "Rio Grande" and "Orellana" . Peers Pinzon baptized the drain as the Marañón River, the voice of indigenous origin probable. It is also possible that the name derives from English maze, representing the enormous difficulties that these men found by exploring the area. In any case, the designation has persisted until today in the Brazilian state of Maranhão and the namesake river in Peru.
River Course:
According to recent studies loos, the Amazon River originates in the foothills of Mount Misti in Arequipa, Peru. Among the various names given to the Amazon River along its course, include successively the following: Lloqueta, Apurimac, Ene, Tambo, Ucayali, Marañón and Amazon.
When the river enters Brazil Solimões River was renamed for a long stretch. Then come back to take the name of the Amazon River at its confluence with the Black River.
After the confluence of the Ucayali and Apurimac river leaves behind the Andean region and enters a flood plain and gently undulating. Also crosses the border between Peru and Colombia and then make tripartite border with Brazil.
In Brazil, the Black River Amazon adds its flow to the muddy, showing the stark contrast of colors of water, virtually no mixed for about 230 km due to the difference in density and temperature, and above all to the same depth and speed of the two streams in the confluence point.

At some points, long distances, the river is divided into two main courses with side channels connected by a complicated system streams, which cut Igapo islands (which rarely exceed 5 m in elevation above the minimum elevation at smaller islands. In the narrows of Óbidos, 600 km from the sea, the river narrows, flowing in a single stream of 1.6 km wide and 300 m deep, with an average speed of 7 km / h.
From the island of Gran Canaria in the curve toward the Black River. 1,000 km downstream, only very low land are similar at the mouth. Vast tracts of land are completely flooded, even deeply, hovering above the water only the tops of the trees.
From near the mouth of Black River to Serpa, on the opposite bank Madeira River, the banks of the Amazon are low, starting to rise in the vicinity of Manaus, forming gentle hills. At Óbidos, the system evolves to become a canyon of 17 m surrounded by low hills. The lower Amazon may have been in the past a gulf in the Atlantic, whose waters eroded the hills near Óbidos.
Only 10% of water transported by the river enters the powerful current of Óbidos, very little of which originates in the northern slope of the valley. The Amazon drainage area west of Óbidos is about 5 million km ² and east of 1 million km ² (about 20%).
In the lower River, the north shore is a series of abrupt plateaus that stretch for about 240 km from the margin opposite the mouth of the river Xingu (in English or adopt a position Shingu singular) to Monte Alegre.
These structures are cut into terraces. Monte Alegre reaches an altitude of several hundred meters. In the southern bank, on the Xingu river runs almost uninterrupted line of low cliffs bordering the alluvial plain and extends nearly to Santarem. The set is a succession of large curves that eventually twist to the southwest and merges with the hills that form the terraced bank of the Tapajós river valley (or better, Tapay).

twice a year between the months of February and March, the Atlantic waters enter the mouth of the Amazon River causing one of the biggest waves in the world and the longest ever recorded.
This tidal wave can reach 4 feet and move up to 17 miles upriver, dragging everything in its path. The natives called "pororoca" , the "big bang" , due to the frightening noise that precedes it, perceptible for half an hour before it reaches its destination.
For years, surfers from around the world come to the mouth of the Amazon with the intention of riding on the "pororoca" although not all succeed.
The phenomenon is often presented as a succession of waves, not too high, but able to take upstream for about an hour.
Those who have ridden this wave, say it is one of the most amazing feelings that may be experienced. "When you go down the Amazon feels like in the middle of the sea. Seems endless, is another world where nothing you learn about the civilization it serves. One is developed by instinct "says a surfer .
