What mountain range runs through much of West Virginia?

The Appalachian Mountains run through much of West Virginia and are a significant geographical feature of the state. This mountain range extends from Canada down to Alabama, and in West Virginia, it creates a diverse landscape characterized by rolling hills, deep valleys, and numerous streams and rivers.

The geological history of the Appalachians is also crucial to understanding West Virginia’s topography, natural resources, and ecosystems. The mountains contribute to the state's rich biodiversity and provide various recreational opportunities, including hiking, camping, and wildlife observation. The Appalachian Mountains are not only vital for the environment but also hold cultural significance, influencing the history and traditions of the people who have lived and thrived in this region.

The other mountain ranges listed do not have a presence in West Virginia; the Rocky Mountains are primarily located in the western United States, the Sierra Nevada primarily runs through California and Nevada, and the Cascade Mountains are found in the Pacific Northwest. Therefore, the Appalachian Mountains are distinctly identifiable as the correct answer regarding the primary mountain range in West Virginia.
