Which of the following describes the land characteristics of the coastal plains?

The coastal plains in Georgia are characterized by flat and sandy terrain, which stems from the geological processes that have shaped the region over time. This type of landscape is primarily composed of sediments that have been deposited by rivers and oceanic movements, leading to wide expanses that are relatively level and sandy. These characteristics make the coastal plains suitable for certain types of agriculture and development, as well as influencing local ecosystems.

In contrast, other options describe landforms that are not typical of the coastal plains. Muddy and hilly landscapes do not accurately capture the predominantly flat topography of the region, while rocky and mountainous features are more representative of Georgia's Blue Ridge and Appalachian areas, which are far inland. The description of wooded and marshy could apply to portions of the coastal plains, particularly in areas with wetlands; however, it does not encompass the entirety of the landscape, which is more defined by its flatness and sandy soil types.
