Conurbations, or densely populated urban areas, have several synonyms that can be used to describe them. Some of these synonyms include metropolis, cityscape, urban sprawl, megalopolis, and industrial center. Metropolis is typically used to refer to a large, thriving city with an extensive cultural and economic scene. Cityscape refers to the physical appearance of a city, including its buildings, skyline, and architectural landmarks. Urban sprawl is used to describe a spreading, uncontrolled growth of a city, often resulting in environmentally unsustainable and socially disconnected neighborhoods. A megalopolis is a group of cities that have merged together to create one vast urban area, while an industrial center is a city that specializes in manufacturing and industry and often has a high population density.
