Power of the Amazon, its description

Amazon - a river with the largest pool in the world, it takes place on the territory of South America.In this article we will look at the power mode, and the Amazon.It was opened by Francisco de Orellana Europeans, who in 1542 crossed the continent in its widest part.Here, according to Francisco, he and his men fought with a tribe of Amazons, so the river got its name.Modern historians believe that this is likely to have been Indian women or Indians themselves with long hair.

tributary of the

By law, the Amazon is considered the deepest river in the world and carries into the ocean 20% of the total volume of fresh water.The water flow is so powerful that, flowing into the Atlantic Ocean, it changes its color and salt composition has over 320 km.The main sources of supply of the Amazon - is its tributaries north (Hawari, Guallaga, Tokantin, Ucayali, Hingham, Hutagi, Rio Preto, teff, Madeira, Purus and Aofi) and southern (Maron, Trombetas, Santa Uatuma, Pastatsa, RioNegro Nalo, Yapura and Putumayo).Their total number is about 200, half of which are navigable.Location tributaries in different hemispheres explains the deep river as floods occur at different times of the year: on the northern tributaries - during the summer season in the Southern Hemisphere (about October-April), on the south - during the summer season in the northern hemisphere (April-October).Thus, it appears that the power sources of the Amazon River is filled with water all year round.

rainy season

rains begin in early March and go three months (until the end of May).In fact, the rain - are important secondary sources of supply after the Amazon River tributaries.Under the impact of heavy rains and river overflows overflows.At this time, the water level could rise by 20 meters, which leads to many kilometers of flooding the surrounding area.Sometimes the flood lasts 120 days, after which the river recedes, and the banks are returning to their former borders.

mouth of the Amazon Estuary

this tropical river forms the largest delta in the world, and its width reaches 325 km.It is interesting to note that it is not acting delta into the ocean, like other rivers, but rather a sort of "pressed" deep.Most likely, this is happening under the pressure of powerful ocean tides.According to witnesses, during the high tide at the mouth of the shaft formed by the water, which sometimes reaches a height of 4 meters.Its strength is felt even at a distance of 1000 km from the delta.The mixing of seawater with river draws him into the mouth of the shark, which rise on the river and there are even at a distance of 3500 km from the ocean.

flora and fauna of the Amazon Rain

both power sources of the Amazon River is very important for the adjacent rain forest, because the water - it is the foundation of life, not only plants, but also animals.There is always a warm stable climate (temperature is 25-28ºS night not below 20 ° C), thanks to this here a huge variety of plants and animals.It should be noted that only 30% of the fauna studied today - more than 1,800 species of birds, fish 1500, more than 250 species of mammals.It is home to such rare animals like the anaconda, jaguar, boa, tapir, a freshwater dolphin, spider monkey, Cayman crocodile, sloth, armadillo.Among the birds are considered to be the most famous hummingbird, toucan, numerous species of parrots.As for insects, they just do not find it here: butterflies alone more than 1,800 species of mosquitoes - more than 200 fish are presented piranhas, tukunare, pirarucu, piraiba and others.

Thus, we can conclude that the power of the Amazon by twoways: through its numerous tributaries, as well as due to the rainy season.This huge river carries significant reserve of fresh water, of great importance for South America.
