A "region" is a specific area that can be defined by various characteristics, such as geography, culture, or economy. Regions can be large, like continents, or smaller, like states or neighborhoods. They help organize space and can influence the way people live and interact. Regions can also be categorized based on climate, natural resources, or political boundaries. For example, the Amazon Rainforest is a region known for its biodiversity, while the Midwest in the United States is recognized for its agricultural production. Understanding regions helps in studying human activities and environmental changes.
