Detailed explanation-1: -Many historians believe the Indus civilisation collapsed because of changes to the geography and climate of the area. Movements in the Earth’s crust (the outside layer) might have caused the Indus river to flood and change its direction.
Detailed explanation-2: -Harappan civilization had collapsed by 1300 BC and the society had seemed to decline by 1900 BC. The “Indus valley civilisation” or “Harappan civilisation” declined around 1800 BCE.
Detailed explanation-3: -The dry spell, lasting 900 years, slowly destroyed its irrigation systems, devastated agriculture and eventually forced Indus people at places such as Harappa and Mohenjo-Daro to abandon the thriving urban culture.
