River valleys provided an ideal environment for agriculture.
Seasonal floods deposited nutrient-rich silt and rivers supplied water for irrigation, allowing stable, abundant food production. Reliable surpluses supported larger, sedentary populations, labor specialization, trade, and centralized governments — the basis of early civilizations. The other choices are incorrect or secondary: rivers could cause natural disasters (flooding), they didn’t inherently shelter from harsh weather, and minerals were not the primary reason settlements formed there.
