While there are some hills and even low mountains in the region, they are not the defining feature.
Here's a breakdown:
* Plains: The Interior Plains are known for their vast, flat, and relatively low-elevation landscapes. This is due to the region being formed by sedimentary rock deposits over millions of years.
* Hills: Some areas, like the Ozark Mountains and the Black Hills, have rolling hills that break up the flatness. These hills are still relatively low in elevation compared to true mountains.
* Mountains: While not as common, there are a few mountain ranges within the Interior Plains region. Examples include the Rocky Mountains in the west and the Appalachian Mountains in the east. However, these mountains are generally found on the edges of the region, not within the core.
So, the Interior Plains are primarily a vast expanse of plains, with some hills and mountains sprinkled around the edges.
