A geographic region is an area defined by specific physical or cultural characteristics. These can include natural features like mountains, rivers, and climate, or human-made aspects such as cities and borders. Geographic regions can vary in size, from small neighborhoods to entire continents, and are often used for purposes like planning, research, and education. Regions can be classified in different ways, such as political regions, which are defined by government boundaries, or ecological regions, which focus on environmental factors. Understanding geographic regions helps in studying patterns of human activity, biodiversity, and resource distribution across the Earth.
