The environmental context for human population characteristics and change
Physical environments — such as climate, soils, and water supply — shape where people live and how populations grow or decline. The environment sets the conditions that make some places densely populated and others nearly empty.
Real World
The Nile Delta has supported dense human settlement for over 5,000 years because its fertile floodplain soils and reliable river water created ideal conditions for agriculture and population growth.
Exam Focus
Always connect physical environment to population outcomes explicitly — state the mechanism, not just the correlation, to access explanation marks.
