a. flat land
The High Plains are primarily characterized as flat land. They are a vast region of elevated terrain that stretches across multiple states in the central United States, including parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The area is known for its expansive grasslands, rolling hills, and relatively flat topography, making it suitable for agriculture and ranching.
Canyons, mountains, and Canadian Breaks (a term referring to rough, eroded terrain) are not typical features of the High Plains.
