South America's geologic structure consists of two dissymmetric parts. In the larger, eastern portion are found a number of stable shields forming highland regions, separated by large basins (including the vast Amazon basin). The western portion is occupied almost entirely by the Andes Mountains.
The upliftment weathering hypothesis suggests that the formations of the uplifted terrains the global climate into an icehouse state and the main factor that influences the global state of the chemical weathering are the global rainfall and the high temperatures, like the rocks in the tropical areas, are exposed to the dry and hot weather conditions.
<u>Similar to that of the cold areas the rocks are exposed to the cold and first action and the interaction of the moisture contents that transform the minerals in the rocks. Which are ongoing processes through the impacts of the oxidation and hydrolysis.
</u>
The formation of the acidic contents in the rocks ios created by the impacts of these temperatures on the rocks mass. The carbonization that is an atmospheric process of the addition to carbon contents to the air and impacts the limestone and the chalk rocks.
is when it contributes towards the contamination and destruction of natural habitats and the wildlife that live in those habitats by exposing them to harmful chemicals that would otherwise not be present over the natural course of things
