WORLD HISTORY

Detailed explanation-1: -The slow eastward migration of monsoons across the Asian continent initially supported the formation of the Harappan civilization in the Indus valley by allowing production of large agricultural surpluses, then decimated the civilization as water supplies for farming dried up, researchers reported Monday.

Detailed explanation-2: -The deep rivers produced by the annual monsoons also meant that fishing was popularly practiced in Harappa. But just as the monsoons were life-giving to ancient India, they were also detrimental. As climate change shifted the monsoon patterns, the fertile soil of Harappa dried out and the area became a desert.

Detailed explanation-3: -The Indus valley cities, which represent the first urbanisation in the sub-continent, are noted for their meticulous urban planning and remarkable drainage system.

Detailed explanation-4: -Both the Indus and the Ganges rivers carried rich silt from the mountains to the plains. When the rivers flooded, the silt spread over the plains and made the soil in the river valleys fertile for farming. Over time, an ancient civilization developed and flourished in these settlements.

Detailed explanation-5: -The monsoons that came to the Indus River Valley aided the growth of agricultural surpluses, which supported the development of cities, such as Harappa. The population came to rely on seasonal monsoons rather than irrigation, and as the monsoons shifted eastward, the water supply would have dried up.
