(1) The northeastern part of Brazilian Highlands receives very less rainfall.
Answers
Answer:
True
Explanation:
Geographical Reasons for Less Rainfall:
Northeast Brazil receives less than 800 mm per year, due to the effects of the anticyclone prevailing in the south Atlantic. Some inland regions receive less than 400 mm/annum!
Rainfall amounts vary greatly from year to year. Droughts in the Nordeste are more likely. Unlike the Amazon, the Nordeste has long been developed, and during serious droughts thousands of people migrate towards the overpopulated cities of the south, or into the Amazon region. However, the coastal area from Recife southward receives more rain, year-round.
Answer:
. i. Brazil receives rainfall from the South- East Trade winds as well as the North- East
Trade winds.
ii. Some parts of the Highlands extend upto the northern coast. The escarpments act
as an obstruction to the South-East trade winds coming from the sea. This causes
orographic type of rainfall in the coastal areas.
iii. Beyond the highlands, as the effect of these winds gets reduced, the region receives
less rainfall.
Due to all these reasons, the north-eastern part of Brazilian Highlands receives very less
rainfall and is called as a rain-shadow region or a ‘Drought Quadrilateral’.
