b) Giving examples, correlate climate and population distribution.

Relation between climate and population:

1. High rainfall causes growth of dense forests where human settlements are very less like the Amazon basin in Brazil and north eastern states in India.
2. Extreme climatic conditions like arid and cold areas reduce human population. For example, savannah in Brazil and high altitudes of Himalayas in India are less populated.
3. Areas with climate that supports agriculture are most populated like northern plains in India and coastal lowlands in Brazil.
4. Areas with moderate climate are also well populated like the deciduous and coastal areas.
