WORLD HISTORY

Detailed explanation-1: -The rivers of ancient India were key to the establishment and continuance of the ancient civilizations present there. The Indus River, which runs south from the Himalayan Mountains through much of modern-day Pakistan and into the Indian Ocean, provided the ancient peoples’ hydration and agricultural fertility.

Detailed explanation-2: -The civilization that developed in the Indus River Valley around 3500-2500 BC, was called the Indus River Valley Civilization. This civilization was largely isolated off from the other early river valley civilizations on all sides by its geography.

Detailed explanation-3: -By 1800 BCE, the Indus Valley climate grew cooler and drier, and a tectonic event may have diverted or disrupted river systems, which were the lifelines of the Indus Valley Civilization. The Harappans may have migrated toward the Ganges basin in the east, where they could have established villages and isolated farms.

Detailed explanation-4: -A wall of the highest mountains in the world-the Hindu Kush, Karakorum, and Himalayan ranges-separates this region from the rest of the Asian continent. a large desert to the east helped protect the Indus Valley from invasion.
