The geographical location of Kolkata, where the city now exists with a metropolitan population of over 15 million, was once on the verge of the continental margin and was also neighbouring the proto-ocean of the Bay of Bengal (BoB). As a consequence, most part of the present Bangladesh territory was under ocean water during the geological past.

Abstract


The geographical location of Kolkata, where the city now exists with a metropolitan population of over 15 million, was once on the verge of the continental margin and was also neighbouring the proto-ocean of the Bay of Bengal (BoB). As a consequence, most part of the present Bangladesh territory was under ocean water during the geological past.
