Why were early civilizations often located near rivers?

• A. Rivers offered defense against enemies.
• B. Rivers provided abundant fish only.
• C. Rivers caused disease.
• D. Rivers offered fertile land for farming.

Answer: (D)

Rivers provide both steady water and nutrient-rich soil, which is what makes river valleys ideal for farming. When floods deposit silt, soil becomes very fertile, so crops grow more reliably and in greater abundance. A dependable water supply also supports irrigation, letting people farm even when rainfall is scarce. This combination makes it possible to produce surplus food, which supports larger populations, specialized work, and the development of cities and governments.

Other benefits like easier transport and trade and some degree of defense can accompany river living, but they are not the primary reason civilizations settled there. Rivers could bring diseases through floodwaters, yet societies adapted and the agricultural advantages often outweighed these risks.
