Final answer:
The Piedmont region is the most populated region of Georgia, characterized by its rolling hills and diverse landscape that supports greater population densities compared to the Coastal Plains and Blue Ridge regions.
Step-by-step explanation:
The most populated region of Georgia is the Piedmont region. This area is characterized by rolling hills and small isolated mountains, including Stone Mountain. The Piedmont's terrain is made up of igneous and metamorphic rock that have been exposed over time.
These features contribute to a diverse landscape that helps support a variety of economic activities, leading to higher population densities. In contrast, the Coastal Plains and the Blue Ridge regions have different geographical features that do not support as much economic development or population density. The Coastal Plains consist of an extensive coastal plain, river basins, and foothills, while the Blue Ridge is known for its high mountain ranges.
