WORLD HISTORY

Detailed explanation-1: -India’s first civilization was built along the Indus river, because it left behind rich silt when it flooded.. This allowed farmers to grow a surplus of food so that civilization could develop. To the east of the Indus, the Ganges River creates a large plain that is also good for farming.

Detailed explanation-2: -The word Punjab means “land of five rivers” and the five rivers are Jhelum, Chenab, Ravi, Beas and Sutlej, all of which finally flow into the Indus.

Detailed explanation-3: -India’s first civilization developed in the Indus Valley because the Indus river system brings a steady source of irrigation water to the Indus Valley that made farming in this otherwise dry region possible. Regular river flooding also deposited fertile soil that was good for crops.
