Question

(Note: You need to include one cause and three effects in your answer.) in only one paragrpah

Answer 1

One potential cause of the decline of the Indus River Valley Civilization is climate change, specifically the shift in monsoon patterns and subsequent droughts. This alteration in climate likely led to decreased river flow and water scarcity, which would have severely impacted agriculture, a cornerstone of the civilization's economy. As crops failed and food became scarce, population densities would have decreased, leading to urban decline and abandonment of cities. Additionally, the resulting stress on water resources might have triggered social unrest and conflict over remaining fertile lands, further destabilizing the community. Lastly, the loss of agricultural productivity and trade networks would have caused economic hardship, contributing to the overall disintegration of the civilization.
