Final answer:
The multi-nuclei model in urban geography describes the development of cities with multiple secondary business districts alongside the traditional central business district (CBD). It helps explain the spatial distribution and dynamics of urban areas.
Step-by-step explanation:
The Multi-nuclei model in urban geography describes the development of cities with multiple secondary business districts alongside the traditional central business district (CBD). These secondary nuclei can include areas of urban development and population growth, multinational corporate establishments, multiple administrative governance, and diverse cultural integration. For example, in Los Angeles, smaller business districts such as Westwood, Wilshire District, Warner Center, Glendale, and Century City compete with the historic CBD for common downtown businesses. The model helps explain the spatial distribution and dynamics of urban areas.
