Virginia's Geography and Natural Resources Uncovered

The video tutorial covers various geographical and geological aspects of Virginia, including the analysis of aerial photographs to identify land types, understanding watersheds, and the economic use of crushed stone. It explains geologic processes in Virginia's coastal plain, mountain formation through plate collisions, and the significance of natural resources like coal. The tutorial also discusses cave formation in the Valley and Ridge Province and identifies wetlands and limestone uses in Virginia.
