Final answer:
The nutrient-rich flood plains of the Indus Valley supported agriculture and facilitated trade, contributing to the spread and development of the Indus Valley civilization.
Step-by-step explanation:
The nutrient-rich flood plains of the Indus Valley played a crucial role in the spread and development of the Indus Valley civilization.
These flood plains were an ideal environment for agricultural productivity, allowing the farmers to cultivate crops such as wheat, barley, peas, and cotton. The annual flooding of the Indus River would deposit fertile silt onto the flood plains, replenishing the soil with nutrients and ensuring high crop yields.
The availability of abundant food resources on the flood plains contributed to the population growth and stability of the Indus Valley civilization. With a stable and abundant food supply, the civilization was able to support a larger population and facilitate the establishment of settled communities.
In addition, the fertile flood plains also provided a natural transportation network for trade and commerce. The Indus River served as a vital waterway for the movement of goods and facilitated trade connections between different regions.
The availability of nutrient-rich flood plains, therefore, played a crucial role in the prosperity and expansion of the Indus Valley civilization.
