What geographical area does the Great Plains refer to?

The Great Plains is defined as a vast grassland that stretches between the Mississippi River and the Rocky Mountains, making it one of the most significant geographical features in the United States. This area covers parts of several states, including Texas, Oklahoma, Kansas, Nebraska, and parts of the Dakotas. The Great Plains is characterized by its flat terrain and significant agricultural activity, particularly the cultivation of crops like wheat and corn, as well as cattle ranching. This geographical region plays a critical role in American history and culture, particularly during the westward expansion of settlers in the 19th century, as it served as a key area for settlement and development. Understanding the Great Plains is essential for appreciating its impact on agricultural practices, indigenous cultures, and the ecological landscape of the United States.
