Ans: Climate:
The health of people living in a favourable climate is good. Timely rainfall
leads to high agricultural production and abundant availability of food. That is
why such areas usually are heavily populated. Large ancient cities existed
near river banks. Temperate and semi hot climates where there is a lot of
rainfall become densely populated. The climate of our northern mountain
ranges is very cold. The climate of Balochistan plateau and desert areas is
extremely hot. That is why these areas are sparsely populated. The northern
areas of the Punjab and Karachi have a temperate climate so they are
densely populated.
