Interior Lowlands
The Great Plains region of North America fits this description. It includes states such as Kansas, Nebraska, and parts of Texas, featuring vast flatlands, rivers like the Missouri and Mississippi, and grassy hills suitable for agriculture and grazing.
rolling hills and narrow valleys
The Interior Lowlands are characterized by flat to rolling terrain with few mountains or hills. They are often covered by grasslands and prairies and are drained by major river systems, making them fertile for agriculture. This region is located in the central part of a continent, away from coastal influences.

The interior plains primarily consist of flatlands, rolling hills, and gentle valleys. This region features features such as prairies, grasslands, and some scattered forests. Additionally, there are river valleys and occasional plateaus, with significant rivers like the Missouri and Mississippi running through parts of the plains. Overall, the terrain is characterized by its relatively low elevation and expansive open spaces.
The Piedmont Region is characterized by rolling hills, plateaus, and low mountain ranges. It features a diverse mix of landforms such as valleys, rivers, and streams. The region is known for its rich soils and moderate climate, as well as its abundance of forests and farmland.

The topography of an area can also mean the surface shape and features themselves.
The terrain in the northeast is varied, ranging from rugged mountains in states like New Hampshire and Vermont to rolling hills and flatlands in states like Massachusetts and Connecticut. There are also many forests, lakes, and rivers throughout the region.
The rolling topography of the Valley and Ridge province in Virginia is primarily shaped by the erosion of folded sedimentary rock layers. This region features parallel ridges and valleys formed from alternating bands of harder and softer rock, where the more resistant layers create ridges while the softer layers erode into valleys. The geological processes of uplift and erosion over millions of years have further sculpted this distinctive landscape, resulting in its characteristic rolling hills and valleys.
