In the Interior Plains, vast stretches of flat land are referred to as plains.

These areas are characterized by their level terrain, which makes them ideal for agriculture and ranching. The plains are home to rich, fertile soils that support various crops and grazing livestock. This flat landscape is a defining feature of the region, contributing to its suitability for farming and its unique ecosystems. The Interior Plains encompass a diverse range of flora and fauna, making them an essential part of North America's geography.
