What common characteristics are found in the Great Plains?

The Great Plains are primarily characterized by vast areas of flat or gently rolling terrain that are dominated by tall grasses and prairies. This region is known for its expansive grasslands that support various types of wild grasses and agricultural activities, making it an essential area for farming, particularly for crops such as wheat and corn. The soil in the Great Plains is typically fertile, which contributes to its designation as an important agricultural zone in the United States.

In contrast, the other options describe environments that do not match the characteristics of the Great Plains. Mountains and rivers are more representative of different geographical regions, deserts and sandy areas pertain to arid landscapes, while lush forests and high elevations are found in mountainous regions, which distinctly differ from the low-lying, grassy topography of the Great Plains. This understanding highlights the unique ecosystem and agricultural importance of the Great Plains in the context of North American geography.
