Harris-Ullman Multiple Nuclei Model AP Human Geography Quiz: Test Your Knowledge

📚 Quick Study Guide

🌍 The Harris-Ullman Multiple Nuclei Model, developed in 1945, proposes that cities don't grow from a single central business district (CBD), but from several independent nuclei.

🏘️ These nuclei attract certain activities and repel others, leading to specialized regions within the city.

🚗 Factors influencing the development of nuclei include:

🚧 Land availability and cost

🏭 Clustering of similar industries

🏘️ Residential preferences

🚄 Transportation hubs

💡 Common urban structures resulting from this model include:

🏢 CBD (Central Business District)

🏭 Wholesale and light manufacturing areas

🏘️ Low-class residential areas

🏡 Middle-class residential areas

🏘️ High-class residential areas

🏭 Heavy manufacturing areas

🛍️ Outlying business districts

🏘️ Residential suburbs

⚙️ Industrial suburbs
