Rainforests have decreased in size primarily due to deforestation. Despite reductions in the deforestation rate over the last ten years, the Amazon rainforest will be reduced by 40% by 2030 at the current rate.


Question 11.

Answer in short:

Why does the deciduous type of vegetation occupy most of India?

The northern part of Brazil is covered by dense forests.


Answer:

The northern part of Brazil is closest to the equator and therefore receives maximum rainfall. Evergreen forests are found in this region around the Amazon basin as it rains throughout the year. These are highly dense in terms of both vegetation and wildlife. Because of the deposition of sediments brought up by the river amazon and as the amazon canal is 150km in width, it forms ideal conditions in terms of soil and water for the growth of dense forests. Also, there is plenty of sunlight in Brazil as the Tropic of Capricorn passes through it.

Evergreen forests are found in this region around the Amazon basin as it rains throughout the year. Because of the deposition of sediments brought up by the river amazon and as the amazon canal is 150km in width, it forms ideal conditions in terms of soil and water for the growth of dense forests. Apart from the numerous species found in the tropical rainforests of north, they are also found in the swamps, grasslands, deciduous forests etc.


Question 15.

Question 16.

Give geographical reasons

Like India, there is need of conservation of forests in Brazil too.


Answer:

A wide variety of wildlife is found in Brazil because it has a high diversity especially in the Amazon rainforests. Evergreen forests are found in this region around the Amazon basin as it rains throughout the year. Because of the deposition of sediments brought up by the river amazon and as the amazon canal is 150km in width, it forms ideal conditions in terms of soil and water for the growth of dense forests. Apart from the numerous species found in the tropical rainforests of north, they are also found in the swamps, grasslands, deciduous forests etc.

Forests in Brazil also need conservation like India because they are under the threat of commercial activities like deforestation and pollution. Traditional agricultural practice like slash and burn is also a cause of destruction. In India, government is taking various initiatives to protect the wildlife of India by bringing in laws against poaching and creating awareness on animal protection like the ‘Project Tiger’, etc.
