WORLD HISTORY

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: -MESOPOTAMIA (3500 B.C. – 1700 B.C.) and 6, 000 years ago, the first river valley civilization developed in Mesopotamia, the region located between the Tigris and Euphrates Rivers (in present-day Iraq).

Detailed explanation-3: -Starting around 3500 B.C., some village cultures developed into urban civilizations in Mesopotamia, Egypt, the Indus Valley, and China. The natural environment of these valleys had a great influence on the development of early civilizations.

Detailed explanation-4: -We’ve also noticed that most of these first civilizations tend to have one thing in common: access to fresh water and fertile soil. It makes sense: you need water and food to build a large, non-mobile society, and so we call these the Early River Valley Civilizations.

Detailed explanation-5: -The Huanghe River valley, as the origin center of millet agriculture, lies between the heartlands of wheat and rice, which gestates the flourishing Neolithic culture based on agriculture.
