THE LONGEST RIVER OF THE WORLD

The Amazon located in South America, is the longest river, the mightiest [1] and the one that has the basin of major surface of our planet. His(her,your) length (6.800 km), it(he,she) overcomes that of the river Nile in more than forty kilometres.
Traditionally the second position(place) is assigned to the Amazon in total length, behind the Nile, though a widespread consensus has never existed on which they are the acceptable points of measurement. The last investigations(researches), however, add approximately 740 km more to the riverbed, which he(she) would place definitively in the first position(place) of the classification of the longest rivers of the world.
According to the most conservative measurements, the river has approximately 6.762 km from length. Nevertheless, an expedition Peruvian - Brazilian who has concluded his(her,your) labors in June, 2007 has calculated 6.800 km .

He presents sections of great variability in the riverbed. In the river mouth the distance of a bank to other one is closely 330 km measured between(among) End do North to Point Patijoca and including Marajó's island (one declare: Maraó), of the size of Denmark and the delta of the river Pará (final section of the river Tocantins), of approximately 60 km from width. The distance of the mouths of the Amazon, formed(trained) by a species(kind) of delta hidden by the action(share) of the tides and of the marine currents, is of approximately 100 km approximately.
Nowadays, for recent reports of investigations(researches), The Geographical Society of Lima, endorsed by entities of the scientific international community, put end(purpose) to the polemic on the origin of the Amazon on having determined that it(he,she) is born in the Andes of the south of Peru and is the longest of the world, superior to river Nile in more than forty kilometres.

From his(her,your) birth in the broken Pile, in the skirts of the Snow-capped mountain Mismi, in Arequipa's department, to 5.150 meters of altitude, up to his(her,your) river mouth in the Atlantic Ocean after crossing Peru and Brazil, it(he,she) reaches a length of 7.062 kilometres.
This it does 391 longer than kilometres the Nile, in Africa, which spreads over 6.671 km, as they said the expert Zaniel Novoa, of the Geographical of Lima Society, and the journalist and exploratory Pole Jacek Palkiewicz, who in 1996 headed a multinational expedition towards the naciente of the Amazon. It(he,she) managed to establish this measurement, which after 12 years was validated by important entities of the scientific international community. Between(among) them they appear the Geographical Society of London, the Academy of Sciences of Russia and the Brazilian Institute.
