The Appalachian Basin is a geological region located in the eastern United States, primarily encompassing parts of West Virginia, Kentucky, Ohio, and Pennsylvania. It is characterized by sedimentary rock formations and is known for its rich natural resources, including coal, natural gas, and oil. The basin plays a significant role in the energy production of the region. This area is part of the larger Appalachian Mountains system, which extends from Canada to Alabama. The basin's formation dates back millions of years, shaped by ancient seas and geological processes. Today, it is an important area for both natural resource extraction and environmental conservation efforts.
