Match each geographic factor on the left with its corresponding impact on regional population density on the right.
- Fertile alluvial river valleysEncourages high population density through agricultural productivity and reliable water supply.
- Extreme desert aridityResults in sparse population density due to severe water scarcity and hostile climate.
- Major industrial and mining complexesCreates dense population clusters driven by employment opportunities and commercial infrastructure.
- Steep and rugged mountain slopesLeads to low population density due to difficult construction, soil erosion, and isolation.
Answer
Fertile alluvial river valleys correspond to high population density via farming and water; Extreme desert aridity corresponds to sparse population density from water shortages; Major industrial and mining complexes correspond to dense clusters driven by employment; Steep mountain slopes correspond to low population density due to physical terrain constraints.
Population density is determined by a combination of physical factors (climate, soil, water supply, relief) and human factors (employment, industrialization, infrastructure). Fertile valleys and industrial centers attract dense populations, whereas arid deserts and steep slopes restrict human habitation.
