Question

The Northern part of Brazil is covered with dense forests and it's because of the deposition of sediments brought up by the river amazon and as the amazon canal is 150km in width and also there is plenty of sunlight in Brazil as the tropic of capricorn passes through it and it's located near the equator.

Answer 1

Amazonia is sparsely populated. There are scattered settlements inland, but most of the population lives in a few larger cities on the banks of the Amazon and other major rivers, such as in Iquitos, Peru, and Manaus and Belém(Brazil). In many regions, the forest has been cleared for soya bean plantationsand ranching (the most extensive non-forest use of the land); some of the inhabitants harvest wild rubber latex, and Brazil nuts. This is a form of extractive farms, where the trees are not cut down. These are relatively sustainable operations in contrast to lumbering or agriculture dependent on clearing the rainforest.

The largest organization fighting for the indigenous peoples in this area is COICA. It is a supra organization encompassing all indigenous rightsorganizations working in the Amazon basin area, and covers the people living in several countries.

Answer 2

Answer:

1) The amount of annual average rainfall is nearly 200 mm in the northern part of Brazil.The annual average temperature of this region is about 28°c.

2) The equator passes through the northern part of Brazil.Therefore,this region receives perpendicular sunrays throughout the year.

3) Due to abundant sunshine and heavy rainfall, vegetation grow with high speed in the region.The life cycle and the density of vegetation is found to be high in this region.Therefore, the northern part of Brazil is covered by dense forests.
