Step-by-step explanation:
A formal region defines an area in which there is uniformity in one or more physical or human characteristics. It is characterized by the presence of a common trait or characteristic across multiple locations. The uniformity can be more pronounced in a core area within the region, while the trait may be less common in the periphery.
For example, the 'Mormon Region' in the United States is a formal region where most people are members of the Church of Jesus Christ of Latter-Day Saints. This region demonstrates uniformity in religious affiliation. Formal regions can also include political boundaries, such as states or countries, and can be defined by physical features like mountain ranges or cultural attributes like language or traditions.
In summary, a formal region is defined by the uniformity of physical or human characteristics across its boundaries.
