Answer to Question 1
Remember that formal regions are areas distinguished by recognized boundaries that have a shared physical, economic, or cultural characteristic. The example of a formal region given in the book is the part of Canada in which the primary language is French (Quebec), or formally defined areas such as the Corn Belt (an economic region), the Rocky Mountains (a physical region), or areas that share a cultural similarity such as Hip Hop, Bluegrass, or Rockabilly music.
A functional region is a region that usually has a transportation linkage that connects cultural, economic, political, and other characteristics that are interwoven into a functional whole. The book gives the example of Chicago as a distinct urban area that has interrelated characteristics that make it a functional, or nodal, region.
