A region is a specific area defined by certain characteristics, such as geography, culture, or climate. Regions can vary in size, from small neighborhoods to large continents. They often share common features, like language, traditions, or natural resources, which help to distinguish them from other areas. Regions can be classified in different ways, such as physical regions, which are based on natural landscapes like mountains or rivers, and political regions, which are defined by governmental boundaries. For example, the Amazon Rainforest is a physical region known for its biodiversity, while Europe is a political region with distinct countries and cultures.
