8. Suburbanization refers to the process by which people move from urban areas to residential areas on the outskirts of the city. This often results in the growth of suburbs, which are residential areas located outside the central city.<br /><br />9. One cause of suburbanization is the desire for more space and a higher quality of life. People may move to the suburbs to escape the congestion and pollution of the city, to have access to more green spaces and natural areas, and to enjoy a more relaxed and family-friendly environment.<br /><br />10. Two reasons for sprawl are the desire for more space and the availability of affordable land on the outskirts of the city. As cities grow and expand, land becomes scarce and expensive, leading people to move to areas where land is more affordable.<br /><br />11. Boomburbs are rapidly growing suburban areas that have experienced significant population growth in recent years. They are characterized by their fast-paced development and high levels of residential growth. Edge cities, on the other hand, are large nodes of employment and commerce that have developed on the outskirts of a major city. They are characterized by their concentration of office buildings, shopping centers, and other commercial activities.<br /><br />12. Megacities are large cities with a population of over 10 million people. They are characterized by their high population density and vast geographic size. Metacities, on the other hand, are even larger urban areas that encompass multiple megacities. They are characterized by their extensive geographic reach and the interconnectedness of their constituent cities.<br /><br />13. A megalopolis is a large network of cities and their surrounding areas that form a continuous urban region. It is characterized by the interconnectedness of its constituent cities and the seamless flow of people, goods, and services between them. Megalopolises are often formed through the process of suburbanization and the growth of cities.
