Question

Give geographical reason:

The northeastern part of the Brazilian Highlands receives very less rainfall.

Answer 1

1. Brazil receives rainfall from the South- East Trade winds as well as the North- East Trade winds.
2. Some parts of the Highlands extend up to the northern coast.
3. The escarpments act as an obstruction to the South-East trade winds coming from the sea. This causes orographic types of rainfall in the coastal areas.
4. 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’.
