how does cultural diffusion occur?
Cultural diffusion can occur by people talking about their ideas/products. When people travel around the world to new places they exchange their ideas/products. *Example: China and Portugal exchange ideas/products in the 1400's.
China's silk trade led to cultural diffusion throughout Eurasia and India. Cultural diffusion, or the spread of ideas and customs from one society to another, occurs in a variety of ways including migration, war and trade among diverse societies. The Silk Road of ancient China is an example of cultural diffusion occurring as a result of trade.
