What do archaeologists identify as one possible reason for the decline of the indus civilization

Some scholars and archaeologists consider a theory related to a sequence of natural and socio-economic factors which determined the decline of the Indus cities.  

They believe that in the Indus Valley region occurred numerous tectonic disturbances which caused earthquakes and changed courses of rivers or dried them up.

These events might have caused a great flood by separating food producing areas from urban centers.

these conditions long with a short growing season made farming difficult.

explanation:

the north has a climate of warm summers and snowy cold winters. the terrain is rocky, hilly, and not good for farming.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
