Which region of Alabama is characterized by rolling hills and limestone?

The Plateau region of Alabama is specifically known for its distinctive rolling hills and underlying limestone geology. This area features gently sloping terrain and a variety of elevations that create a picturesque landscape. The limestone in this region contributes to the soil composition and influences the types of vegetation that thrive there.

In contrast, other regions present in Alabama, such as the Highlands, Piedmont, and Flatlands, have their own characteristics but do not embody the distinct rolling hills and limestone backdrop that defines the Plateau. Each of these areas has its geological features, yet the Plateau uniquely combines elevation changes with limestone, making it the correct answer regarding the described landscape of rolling hills.
