City zones are designated areas within a city that are planned for specific uses, such as residential, commercial, or industrial purposes. These zones help organize urban development and ensure that different activities can coexist without conflict. For example, a residential zone may contain homes and apartments, while a commercial zone includes shops and offices. Zoning regulations dictate what can be built in each zone and how land can be used. This helps maintain order and safety in urban environments. Additionally, city planners often consider factors like traffic, public services, and environmental impact when creating these zones to promote sustainable growth.
