Answer:
North America, the Caribbean, and Latin America are all examples of formal regions.
Step-by-step explanation:
Formal regions are regions that are defined as such based on one or more characteristics that are shared by the inhabitants of the region. In some cases, the boundaries between formal regions are not visible, while in other cases there are geographical features that clearly distinguish them.
North America, the Caribbean, and Latin America are all examples of this type of region. The majority of the population in each of them has characteristics that are common, but also distinguish them from the other regions. These shared characteristics can be seen in the dominant culture (English-based, Spanish/Portuguese-based, a mixture of several), religion, lifestyle, race, ethnicity, language, etc.
