Final answer:
Accurate statements Ziva should share include that regions are based on shared characteristics, the US can be divided into political and economic regions, and there are multiple ways to divide regions. However, it's incorrect to say regions are only based on state locations.
Step-by-step explanation:
Ziva is correct in sharing that "Regions are determined by the shared characteristics in an area." This understanding of regions in the United States is essential for comprehending how geographers categorize different areas by various criteria such as climate, vegetation, language, or religion.
Furthermore, she can also accurately inform her friend that "The United States can be divided into political and economic regions," and it is true that "There are many different ways that regions can be divided in the United States." However, stating that the United States can only be divided based on the location of states is incorrect, as regions can also be determined by cultural traits, economic functions, and other factors.
