Step-by-step explanation:
Ocean-centered geography explains how two cities that are halfway around the world share culture traits, people, and ideas primarily through shared trade. The ocean acts as a connector, enabling the movement of goods and services between different regions. For example, the Silk Road facilitated the exchange of goods and ideas between Europe and Asia. This exchange of trade leads to the transmission of cultural practices, beliefs, technologies, and even languages. Cities along trade routes become melting pots of diverse cultures, fostering the sharing and mixing of ideas.
