Final answer:
Virginia is the state featuring the Appalachians in the west, with the eastern region including the Blue Ridge Mountains, and the Allegheny Mountains in its western part. The state showcases a diversity of geological features and resources throughout these mountain ranges.
Step-by-step explanation:
The state that has the Appalachians in the west, the Blue Ridge Mountains in the east, and the Allegheny Mountains in the western part is Virginia. The Appalachian Mountains are a significant feature in this state, and the region offers a rich tapestry of geological history and landscapes. The Piedmont Province, located southeast of the Blue Ridge Mountains, consists of lower rolling hills and small isolated mountains, while the west side is characterized by the Appalachian Plateau. The Province is an uplifted and largely undeformed region, rich in geological resources.
The many formations within the western Appalachians, including the Valley and Ridge Province, the Blue Ridge Province with its ancient igneous and metamorphic rocks, and the Appalachian Plateau with preserved fossils, coal in West Virginia, and iron in Alabama, highlight the varied and rich geology of the region.
