Question

How floods were the main reason for thevdecline of harappan civilisation

Answer 1

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

The massive floods in the Indus must have been a potent cause for the extinction of the Harappan culture. The point is proved by the silt-clay that covers the collapsed houses at Mohenjo-Daro. Repeated floods must have forced the people to flee the inundated places and set up permanent habitat elsewhere.

Answer 2

Answer:

it's not mention in any book that harrapan civilization was declined all the historians have just predicted that .Perhaps it would be any flood, earthquake or aryans had attacked on their society or there would be any spread of deadliest disease which led to end of harrapan civilization. So, overall we cannot say how it led to an end .
