Which of the following is the best definition of a formal

region? (1 point)
a region defined by how it is perceived by people, either
by those within the region or by outsiders
a contiguous area on Earth’s surface, with either a formal
or loosely defined boundary, characterized by one or more
similarities that make it distinct from other areas
a region with a clear political or physical boundary or set
of shared characteristics
a region defined by a uniting purpose, process, or
function, including educational, economic, or civic
purposes

a region with a clear political or physical boundary or set

of shared characteristics

The best definition of a formal region is:

a region with a clear political or physical boundary or set of shared characteristics

To determine the best definition of a formal region, let's analyze each option and see which one aligns most accurately with the concept.

1. A region defined by how it is perceived by people, either by those within the region or by outsiders.
This definition suggests that a formal region is determined by people's perceptions. However, formal regions are typically defined by more objective criteria, such as physical or political boundaries, rather than subjective perceptions.

2. A contiguous area on Earth’s surface, with either a formal or loosely defined boundary, characterized by one or more similarities that make it distinct from other areas.
This definition captures the essence of a formal region by emphasizing the presence of specific similarities that differentiate it from surrounding areas. The mention of a boundary also aligns with the concept of a formal region having a defined area.

3. A region with a clear political or physical boundary or set of shared characteristics.
This definition emphasizes the presence of a clear boundary or shared characteristics, reinforcing the notion of a formal region being distinct and well-defined.

4. A region defined by a uniting purpose, process, or function, including educational, economic, or civic purposes.
This definition expands the concept of a formal region to include regions with shared purposes or functions. While this can be a valid characteristic of certain regions, it does not encompass the full definition of a formal region.

Based on these analyses, option 3 - "a region with a clear political or physical boundary or set of shared characteristics" - appears to be the best definition of a formal region. It highlights the importance of boundaries and shared characteristics, which are key elements in defining a formal region.
