Question

Define population density. Explain the physical factors affecting the population density in the world.

Hint:

Physical features like terrain, climate, and water availability determine how densely populated an area is.

Answer 1

Population density quantifies individuals per unit of area, typically per square kilometer.Physical determinants of population density are:
Relief: Plains and lowlands exhibit higher population density than mountainous or rugged regions.
Climate: Moderate climates with sufficient rainfall are more densely populated than extreme cold or hot deserts.
Soil Fertility: Arable land supports agriculture, drawing concentrated populations.
Water Availability: Settlements concentrate near water sources such as rivers, lakes, and coastlines.
Natural Hazards: Regions susceptible to natural disasters like floods, earthquakes, or droughts generally have lower population densities.
