Terrain and Ecology. Tropical rain forest – the biggest on Earth – covers two-thirds of the Amazon Basin. Much of this lies on the terra firme uplands, but seasonally inundated bottomland rain. Terrain. Rainforests have a constant rain flow which creates muddy, mushy, soil. The abundance of rainfall drains the nutrients out of the soil. There are very many trees and plants. The Tropical rainforest has buttressed trunks, evergreens, ferns, and mosses.
Amazon Rainforestlarge tropical rainforest occupying the drainage basin of the Amazon River and its tributaries in northern South America and covering an area of 2, square miles 6, square km.

Amazonia is the largest river basin in the world, and its forest stretches from the Atlantic Ocean in the east to the tree line of the Andes in the west.

The constant rain flow causes the soil to be very mushy, and it also drains the nutrients out of it, so areas where plant life has been destroyed have a hard.
The enormous tropical rain forest carpeting the Amazon Basin in north-central South America is famous for its globally outstanding biodiversity and luxuriant suite of indigenous human cultures.
The Amazon Basin is one of several major structural lowlands in South America, separated by up-warped highlands; others are the Orinoco and Chaco-Pampa basins. Sprawling across about 2.
The ancient bedrock underlying the basin is mostly covered by thick layers of sedimentary materials, stemming both from the depositions of rivers draining the Andes and surrounding highlands and from a period when the basin lay beneath a shallow sea, some 2.
Topographically, the basin cants extremely subtly to the east. The great Amazon River, which flows more than 4, miles across the basin to the Atlantic, likely once drained to the Pacific, but the uplift of the Andes shifted its course to make the epic eastward journey. The normal flooding cycles of the Amazon and its tributaries see the rivers spilling their banks and fanning out over the gentle topography of the basin floor.
So great is the weight of the annual flood that the South American continent depresses several inches as it spreads and rebounds as it retreats. The Amazon Basin is bounded on three sides by highlands and one by the Atlantic Ocean. West rise the Andes, source of the Amazon and the second-highest mountain range on Earth, after the Himalayas. Mount Mismi, the volcano in the Peruvian Andes that sources the Amazon, looms over 18, feet high.
North of the basin are the Guiana Highlands; south of it are the Brazilian Highlands. The Guiana and Brazilian highlands angle toward each other in the east, so the Amazon Basin narrows as it approaches the Atlantic.
Tropical rain forest — the biggest on Earth — covers two-thirds of the Amazon Basin. The annual flooding of the low forests allows river beasts — freshwater dolphins, pirarucus, caimans, electric eels and others — to wander among buttressed trees and take advantage of forest resources. The tambaqui, for example, is an herbivorous, heavy-jawed fish that feeds on fallen, floating fruits in the flood time — helping disperse the seeds of rubber trees and other species as it does.
