Overview

Virginia is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond and Virginia Beach is the most-populous city.

The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the growing plantation economy, but also fueled conflicts both inside and outside the colony. Virginia was one of the Thirteen Colonies during the American Revolution, becoming part of the United States in 1776. The state was split by the American Civil War in 1861, when Virginia's state government in Richmond joined the Confederacy, but many in the state's western counties remained loyal to the Union, helping form the state of West Virginia in 1863.

Geology and terrain

The Chesapeake Bay separates the contiguous portion of the Commonwealth from the two-county peninsula of Virginia's Eastern Shore. The bay was formed from the drowned river valley of the ancient Susquehanna River. Many of Virginia's rivers flow into the Chesapeake Bay, including the Potomac, Rappahannock, York, and James, which create three peninsulas in the bay, traditionally referred to as "necks" named Northern Neck, Middle Peninsula, and the Virginia Peninsula from north to south. Sea level rise has eroded the land on Virginia's islands, which include Tangier Island in the bay and Chincoteague, one of 23 barrier islands on the Atlantic coast.

Great Falls is on the fall line of the Potomac River, and its rocks date to the late Precambrian. The Tidewater is a coastal plain between the Atlantic coast and the fall line. It includes the Eastern Shore and major estuaries of Chesapeake Bay. The Piedmont is a series of sedimentary and igneous rock-based foothills east of the mountains which were formed in the Mesozoic era. The region, known for its heavy clay soil, includes the Southwest Mountains around Charlottesville. The Blue Ridge Mountains are a physiographic province of the Appalachian Mountains with the highest points in the Commonwealth, the tallest being Mount Rogers at 5,729 feet (1,746 m). The Ridge-and-Valley region is west of the mountains, carbonate rock based, and includes the Massanutten Mountain ridge and the Great Appalachian Valley, which is called the Shenandoah Valley in Virginia. The Cumberland Plateau and Cumberland Mountains are in the southwest corner of Virginia, south of the Allegheny Plateau. In this region, rivers flow northwest, with a dendritic drainage system, into the Ohio River basin.
