Which physiographic region is described as being found in North Alabama and comprised of limestone valleys and uplands with rolling hills?

The physiographic region described, characterized by limestone valleys and uplands with rolling hills, is appropriately identified as a plateau. Plateaus are largely flat regions elevated significantly above the surrounding area, often exhibiting layered rock formations like limestone, which can lead to the development of valleys and hills due to erosion and weathering processes. This specific type of landform is commonly associated with North Alabama, where the geology is influenced by limestone bedrock, resulting in the unique terrain with both elevations and depressions.

While the other options include various landforms, they do not accurately describe the features found in North Alabama. The Coastal Plain typically refers to flat, low-lying areas near coastlines, the Mountain region usually encompasses higher elevations with significant relief and steep slopes, and the Valley generally denotes low-lying areas between hills or mountains but does not capture the elevated, flat nature present in a plateau. Therefore, identifying this area as a plateau aligns with its distinctive geological and topographical characteristics.
