Amazon Basin

The Amazon Basin was formed by the movement of the tectonic plates. The Gondwana Plate split causing the South American plate to collide with the Pacific plate, resulting to the Pacific plate subducting beneath the South American plate. Furthermore the Pacific plate was exposed to hot magma which is beneath the earth surface. However, the Pacific plate melted and broke up. The broken chunk of the Pacific plate popped up to the surface finding a weak spot in the younger Andes Mountains. As a result this lead to a volcanic eruption forming a bigger Andes Mountains. The Andes Mountains then erode causing soft rock to be carried down the mountain by rain forming the Amazon Basin. Leaving the Andes Mountain to increase in heights.

Younger Andes Mountains were formed as the Gondwana continent split. This caused the South America plate to collide with the Pacific plate, then the Pacific plate sub ducted. The Pacific plate is then exposed to hot magma. After that the Pacific plate then begins to melt and break up into chunks. The broken chunks pop up to the surface, it finds a week spot in the younger Andes Mountains. Then suddenly volcanic eruptions occur. Finally the rock on top of the Andes Mountains is very soft, it could easily be moved across the ground. It rains and the erosion gets very…

The processes which are responsible for the evolution and the change of the Amazon rainforest is the movement of tectonic plates which were the movement of the pacific plate and also the american plate which then formed a mountain called the Andes Mountain.

The next process which leads to further change within the Amazon rainforest is the denduation process where it is raining or known to be raining and than it leads to the rocks on the mountain becoming slippery and than the rock been eroded slippery and than it leads to transportation. The rocks flow down to the Amazon Basin causing a new position or it's deposited causing a new position.

Therefore these processes repeat continously which causes the changes.

NOW THE WHOLE THING…
Younger Andes Mountains were formed as the Gondwana continent split. This caused the South America plate to collide with the Pacific plate, then the Pacific plate sub ducted. The Pacific plate is then exposed to hot magma. After that the Pacific plate then begins to melt and break up into chunks. The broken chunks pop up to the surface; it finds a week spot in the younger Andes Mountains. Then suddenly volcanic eruptions occur. Finally the rock on top of the Andes Mountains is very soft; it could easily be moved across the ground. It rains and the erosion gets very strong and falls down, this is how the largest amazing basin in the whole world called the Amazon was created.

The amazon landscape is the result of these changes. The younger Andes Mountains were formed as the dividing Gondwana continent’s western region split causing the South America plate to collide with the pacific plate resulting in volcanic eruptions and mountain building.
The younger Andes began to erode immediately and quickly the result of its increased height and softness of rock. The eroded material was carried by water to basin between the Andes and the old plateaus. Eventually this built a basin beyond the plateau to the current Atlantic coastline.
