Functions of Cities • Security, defense • Religious centers • Trade centers (local and long distance) • Government administration • Manufacturing centers • Service centers
How Functions Change • Rio de Janeiro – Move of Brazil’s capital city from Rio de Janeiro to Brasilia • Pittsburgh – Early function connected to defense, then became steel manufacturing center, later shifted to diverse services • New York City – Changes in trade patterns, trade from Great Lakes via Eerie Canal, worldwide trade and financial center • Mining Towns – “ghost” towns – resource depletion
