A conurbation is an extended urban area that results from the merging of multiple cities or towns, typically characterized by a continuous network of built-up areas and infrastructure. This phenomenon often occurs due to population growth and urban sprawl, leading to a densely populated region where the boundaries between urban centers become blurred. Examples include the Greater Tokyo Area and the Northeastern U.S. megalopolis. Conurbations can create significant economic, social, and environmental impacts on the regions they encompass.
