Which of the following best defines the term 'region' in geographical context?

In a geographical context, the term "region" is best defined as a section distinguished by natural characteristics. This definition encompasses various aspects of the environment, such as topography, climate, vegetation, and ecosystems that define an area. Regions can be identified through both physical features, like mountains and rivers, and biological features, such as specific fauna and flora that thrive in certain environments.

Understanding a region in this way allows for the study of environmental processes, biodiversity, and the relationship between different physical features and human activities. While territories with governmental control and economic functions are significant in human geography, they do not capture the full essence of a region as understood in a physical geography context. Similarly, while human occupation can characterize certain regions, it is the natural characteristics that primarily differentiate and define regions in their most fundamental sense.
