Answer the following questions:

Why has mining not developed in the western parts of Brazil?

Brazil is rich in many natural resources like manganese, bauxite, iron ore and coal that contributes largely to its national income. Majority of mining activities is carried out in the eastern part of Brazil. It is highly limited in the western and interior parts because of the dense, impenetrable forests in the Amazon basin. The resources in these parts are highly inaccessible, and knowledge about them is limited. Thus, inaccessibility and lack of knowledge due to forest cover and river basins are the main reasons why resources in the western parts are not highly exploited.
