Which region of Georgia is primarily characterized by rivers draining into the Gulf of Mexico?

The East Gulf Coastal Plain is primarily characterized by rivers that drain into the Gulf of Mexico due to its geographical location and hydrology. This region includes various river systems that flow toward the Gulf, taking advantage of the gentle slopes and the natural drainage patterns present in this area. The broad, flat terrain of the Coastal Plain allows for the formation of numerous rivers, many of which ultimately lead to the Gulf.

In contrast, the other regions mentioned have different characteristics. The Piedmont is known for its rolling hills and is situated between the mountains and coastal plain, with rivers typically flowing toward the Atlantic Ocean, not the Gulf. The Blue Ridge region features mountainous terrain with rivers that primarily flow eastward. Lastly, the Appalachian Ridge and Valley region contains hilly and valley terrains and is not directly associated with drainage patterns leading to the Gulf of Mexico. Thus, the East Gulf Coastal Plain stands out as the region where rivers primarily drain into the Gulf.
