Question

Observe figures and answer the questions.

1. In which area is population greatly concentrated?
2. In which area is the distribution of population sparse?
3. Prepare a note on factors responsible for the uneven distribution of population based on study of Brazil you have made so far.
4. Identify the type of map showing distribution.

Answer 1

1. The population is concentrated in Sao Paulo, Rio de Janeiro, and the southeastern coastal regions.
2. The Amazon Basin in the northern part and the central and western parts of Brazil have a sparse distribution of population.
3. The distribution of population in Brazil is uneven:
   1. There is sparse population in the Amazon Basin due to hot and humid climate, heavy rainfall, dense forests, inaccessibility.
   2. The population is low in the swampy areas of Pantanal.
   3. Low population is found in the central and western part of Brazil due to lack of minerals, low rainfall, hot and dry climatic conditions.
   4. The distribution of population is moderate in Brazilian Highlands.
   5. High population is found in the coastal regions and the southern part of Brazil. This is due to flat fertile land and abundant availability of minerals due to which agriculture, industries and trade have developed.
4. The type of map showing the distribution of population is a dot map.
