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: -There were deserts to the east and west of the Nile River, and mountains to the south. This isolated the ancient Egyptians and allowed them to develop a truly distinctive culture. Other natural barriers included the Mediterranean Sea to the north and the Red Sea to the east.
Detailed explanation-3: -The major four river valley civilizations were located along the Indus River, the Yellow River, the Nile River, and the Tigris and Euphrates Rivers in Mesopotamia. Although each of these was located along a river for similar reasons, they had very different political systems, religions, languages, and cultures.
