Physical Features of Oklahoma

Oklahoma features a diverse landscape that transitions from forests and hills in the east to plains and mesas in the west. The eastern region includes the Ozark Plateau and Ouachita Mountains with wooded hills and valleys, while central Oklahoma consists of rolling plains and grasslands. Western Oklahoma becomes more arid, with flat plains, mesas, and canyons. Major rivers such as the Arkansas and Red Rivers shape the terrain, and numerous lakes and reservoirs add to the state’s varied geography.
