Answer:
Explanation:
These types of civilizations tend to develop and grow near a river for various reasons. The most important reason, is because they had an easy access for a reliable source of water that helped with agriculture and other needs that arose at the time. With a near river and constant raining, these civilizations made it possible to grow more crops than needed, therefore they could sustain an agricultural village. Additionally, this situation allowed some members of the community to work and engage in non-agricultural activities, such as construction (for buildings and cities), metalworking, trade and many other tasks. With the help of boats, they could transport people and goods in a sufficient way; allowing them to develop and grow in trade.
