Why Brazilian highlands called Brazilian shild
Answers
Explanation:
The Brazilian Shield or the Brazilian Highlands are a broad geographical area that spans most of the central, southern and eastern parts of Brazil. It spans for about 45,00,000 square km and includes nearly half of Brazil's land area.
Additionally, a large amount of Brazil's population resides in these highlands. A large number of people also live in the narrow coastal belt that is just adjacent to these highlands. Very old lava and basalt flow in the area created this highland.
Anyway, the era of potent geophysical tumult is now over and there is at present, no volcanic eruption or any seismic activity. Soil erosion in the area has also been responsible for making these Highlands.
They have helped in the creation of sedimentary deposits by slowly wearing out of mountains. The Brazilian Shield is known for the outstanding diversity that is found here.
In the area, many types of climatic conditions, thousands of plants and animal species, many different available biomes and a lot of different soil types.
