&nbsp; &nbsp; It is&nbsp;a&nbsp;moist&nbsp;broadleaf forest&nbsp;that covers&nbsp;most of the&nbsp;Amazon Basin&nbsp;of South AmericaThis basin&nbsp;encompasses&nbsp;seven million&nbsp;square kilometers,&nbsp;of which five&nbsp;and a half millionsquare kilometers are covered&nbsp;by&nbsp;rain forest.&nbsp;This region&nbsp;includes&nbsp;territory&nbsp;belonging to nine&nbsp;nations.&nbsp;Most of the forests&nbsp;is contained&nbsp;within Brazil,&nbsp;with 60% of the forest,followed&nbsp;by Peru&nbsp;with 13%&nbsp;and&nbsp;small amounts&nbsp;in Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname&nbsp;and France&nbsp;(French Guiana).&nbsp;States&nbsp;or departments in&nbsp;four&nbsp;nationsbear the name&nbsp;Amazonas&nbsp;for it.&nbsp;The Amazon&nbsp;represents&nbsp;over half the&nbsp;planet's remainingrainforests&nbsp;and comprises&nbsp;the most&nbsp;biodiverse&nbsp;tropical forest&nbsp;in the world.&nbsp;It is&nbsp;one&nbsp;of the six&nbsp;major biomes.

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Weather:





&nbsp; &nbsp; In the&nbsp;Pleistocene&nbsp;the climate of Amazonia&nbsp;alternated between&nbsp;cold-dry, hot-humid&nbsp;and hot-dry.&nbsp;In the last phase&nbsp;cold-dry&nbsp;for about&nbsp;18 or&nbsp;12 thousand years, the&nbsp;Amazon climatewas&nbsp;semi-arid,&nbsp;and the maximum&nbsp;humidity&nbsp;occurred&nbsp;seven thousand years ago.&nbsp;In phasesemi-arid&nbsp;prevailed&nbsp;open vegetation&nbsp;such as&nbsp;savannah and&nbsp;caatinga, with&nbsp;"safe havens" where&nbsp;the forest&nbsp;survived.&nbsp;Currently&nbsp;the savannah&nbsp;subsist&nbsp;in shelters&nbsp;in the forest interior.


&nbsp;Currently,&nbsp;the climate&nbsp;in the Amazon rainforest&nbsp;is equatorial, hot and humid&nbsp;due&nbsp;to the proximity to&nbsp;the equator&nbsp;(the&nbsp;continuous&nbsp;Atlantic Forest),&nbsp;with temperature&nbsp;varying littlethroughout the year.&nbsp;The rains&nbsp;are abundant,&nbsp;with&nbsp;average&nbsp;annual&nbsp;rainfall&nbsp;ranging from1500&nbsp;mm to&nbsp;1700&nbsp;mm&nbsp;and may&nbsp;exceed&nbsp;3000&nbsp;mm&nbsp;at the mouth of&nbsp;the Amazon River andthe coast of&nbsp;Amapá.&nbsp;The rainy season&nbsp;lasts&nbsp;six months

&nbsp; &nbsp; Tropical moist forests are&nbsp;very&nbsp;biodiverse&nbsp;biomes&nbsp;and rainforests&nbsp;of the Americas areconsistently more&nbsp;biodiverse&nbsp;than the&nbsp;rainforests&nbsp;of Africa and&nbsp;Asia.As the largesttract of tropical forest&nbsp;in America, the&nbsp;Amazon rainforests&nbsp;have&nbsp;unparalleled&nbsp;biodiversity.One in ten&nbsp;known species&nbsp;in the world live&nbsp;in the Amazon rain florest.This&nbsp;is&nbsp;the largest collection of&nbsp;living plants and&nbsp;animal species&nbsp;in the world.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
