Answer 1

Geographical Factors Influencing the Distribution of the World’s Population

The distribution of the world’s population is highly uneven. Geographical factors play a fundamental role in determining where people can live and thrive. The main geographical factors are:

a) Availability of Water:

Water is the most critical resource for human survival. It is essential for drinking, cooking, agriculture (irrigation), industry, and transport. Consequently, human settlements have historically flourished in river valleys and coastal plains where freshwater is abundant. Densely populated regions like the Nile Valley, the Indo-Gangetic Plains, and the river basins of China are prime examples. Conversely, arid regions like deserts have very sparse populations due to water scarcity.

b) Climate:

Climate significantly influences population distribution as it affects agriculture and human comfort. Most people prefer to live in temperate climates with distinct seasons and reliable rainfall. These conditions are ideal for growing a variety of crops. Areas with extreme climates, such as the intensely hot and humid equatorial rainforests, the cold polar regions, or extremely hot and dry deserts, are sparsely populated because they pose challenges to settlement and agriculture.

c) Topography (Landforms):

The physical shape of the land is a major factor. Flat plains and gentle slopes are preferred for human settlement because they are easy to build on, cultivate, and develop transport networks. The great plains of North America, Europe, and Asia are densely populated. In contrast, mountainous and rugged terrains are sparsely populated due to their steep slopes, poor soil quality, and difficulties in transportation and farming.

d) Soils:

The fertility of the soil is directly linked to agricultural productivity and the ability of a region to support a large population. Regions with fertile, loamy soils, such as those found in river deltas and volcanic areas, are capable of supporting intensive agriculture and thus have high population densities. Areas with thin, rocky, or infertile soils, like in mountainous regions or leached tropical soils, cannot support large populations.
