Regions are defined areas that can be characterized by various factors such as geography, culture, or political boundaries. They can range from large continents to smaller administrative divisions, each with its own unique features and significance. Understanding regions helps in studying human interactions, environmental conditions, and economic activities. In a global context, regions play a crucial role in international relations and trade. For instance, European Union is a political region that fosters economic cooperation among its member states. Similarly, cultural regions like Latin America share common historical and social traits, influencing their identity and development.
