GENERAL KNOWLEDGE

Detailed explanation-1: -Solution: In the early ages of human existence, the greatest civilisations existed near the river valleys. The rivers acted as a reliable source of water for agriculture and other human needs. The land beside the river was very fertile which facilitated agriculture, hence fulfilled the need of surplus food.

Detailed explanation-2: -Rivers. Most ancient civilizations were formed around major rivers, especially when those led to the sea. Living far away from the rivers mostly meant tribes had to be nomadic. Rivers provide civilizations with a supply of fresh and clean water, which they can use for crops, animals, and themselves.

Mesopotamian cities became self-run civil governments. One of the cities within this civilization, Ur, was the first literate society in history.

Detailed explanation-4: -Civilizations developed around rivers because their waters provided places to hunt and fish. Also, as the rivers flooded, the lands around them became fertile. This allowed them to support farming. This is especially true of the Nile River, which flooded the same time each year.
