Final answer:
Both the Sector Model and the Multiple Nuclei Model feature a central market or CBD, with the former having wedge-shaped zones extending from it, and the latter having multiple business districts or nuclei throughout the city.
Step-by-step explanation:
In both the Sector Model and the Multiple Nuclei Model, there is a central market or Central Business District (CBD). In the Sector Model, developed by Homer Hoyt, the city is structured with wedge-shaped zones that extend from a central CBD, influenced by factors such as transportation routes and wind patterns.
Meanwhile, the Multiple Nuclei Model suggests that a city doesn't revolve solely around a single CBD; instead, it consists of multiple smaller business districts or nuclei that can serve similar functions to the CBD, such as banking and legal services.
Cities like Los Angeles exemplify this with their multiple business districts scattered around the city, challenging the dominance of the historic central CBD.
