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 is defined as the number of people living per unit area, usually per square kilometer. Physical factors affecting population density include:
Relief: Flat plains and lowlands have higher population density compared to mountainous or rugged terrains.
Climate: Moderate climate zones with adequate rainfall are more densely populated than extreme cold or hot deserts.
Soil Fertility: Fertile soils support agriculture, attracting dense settlements.
Water Availability: Proximity to rivers, lakes, and coasts influences population concentration.
Natural Hazards: Areas prone to floods, earthquakes, or droughts tend to have lower population density.
