Author Virginia

erican Revolution and joined the Confederacy in the American Civil War, during which Richmond was the Confederate capital and the state of West Virginia separated. Although traditionally conservative and historically part of the South, both major national parties are competitive in modern Virginia.[6] The state government, home to the oldest legislature in the Americas, has been repeatedly ranked most effective by the Pew Center on the States.[7] It is unique in how it treats cities and counties equally, manages local roads, and prohibits its Governors from serving consecutive terms. Virginia's economy has many sectors: agriculture in places like the Shenandoah Valley; federal agencies in Northern Virginia, including the Department of Defense and CIA; and military facilities in Hampton Roads, home to the region's main seaport. The growth of the media and technology sectors have made computer chips the state's leading export, with the industry based on the strength of Virginia's public schools and universities.[8] Virginia does not have a major professional sports franchise, but is home to several prominent collegiate sports programs. Virginia has a total area of 42,774.2 square miles (110,784.67 km2), including 3,180.13 square miles (8,236.5 km2) of water, making it the 35th-largest state by area.[9] Virginia is bordered by Maryland and Washington, D.C. to the north and east; by the Atlantic Ocean to the east; by North Carolina and Tennessee to the south; by Kentucky to the west; and by West Virginia to the north and west. Due to a peculiarity of Virginia's original charter, its boundary with Maryland and Washington, D.C. does not extend past the low-water mark of the south shore of the Potomac River (unlike many boundaries that split a river down the middle).[10] The southern border is defined as the 36° 30? parallel north, though surveyor error led to deviations of as much as three arcminutes.[11] The Chesapeake Bay separates the contiguous portion of the Commonwealth from the two-county peninsula of Virginia's Eastern Shore. The bay was formed following a meteoroid impact crater during the Eocene.[12] Many of Virginia's rivers flow into the Chesapeake Bay, including the Potomac, Rappahannock, James, and York, which create three peninsulas in the bay.[13][14] Geographically and geologically, Virginia is divided into five regions from east to west: Tidewater, Piedmont, Blue Ridge Mountains, Ridge and Valley, and Cumberland Plateau, also called the Appalachian Plateau.[15] The Tidewater is a coastal plain between the Atlantic coast and the fall line. It includes the Eastern Shore and major estuaries which enter the Chesapeake Bay. The Piedmont is a series of sedimentary and igneous rock-based foothills east of the mountains which were formed in the Mesozoic.[16] The region, known for its heavy clay soil, includes the Southwest Mountains.[17] The Blue Ridge Mountains are a physiographic province of the chain of Appalachian Mountains with the highest points in the state, the tallest being Mount Rogers at 5,729 feet (1,746 m).[18] The Ridge and Valley region is west of the mountains, and includes the Great Appalachian Valley. The region is carbonate rock based, and includes Massanutten Mountain.[19] The Cumberland Plateau and the Cumberland Mountains are in the south-west corner of Virginia, below the Allegheny Plateau. In this region rivers flow northwest, with a dendritic drainage system, into the Ohio River basin.[20] Because of the areas of carbonate rock, more than 4,000 caves exist in Virginia, with ten open for tourism.[22] The Virginia seismic zone has not had a history of regular activity. Earthquakes are rarely above 4.5 on the Richter magnitude scale because Virginia is located centrally on the North American Plate. The largest earthquake, at an estimated 5.9 magnitude, was in 1897 in Blacksburg.[23] Coal mining takes place in the three mountainous regions at 40 distinct coal beds near Mesozoic basins.[24] Besides coal, resources such as slate, kyanite, sand, and gravel are mined, with an annual value over $2 billion as of 2006.[25] The climate of Virginia varies according to location, and becomes increasingly warmer farther south and east. Most of the state has a humid subtropical climate (Köppen climate classification Cfa), from the Blue Ridge Mountains and southern Shenandoah Valley to the Atlantic coast.[26] In the Blue Ridge Mountains, the climate becomes subtropical highland (Köppen climate classification Cfb).[27] Virginia experiences seasonal extremes, from average lows of 26 °F (?3.3 °C) in January to average highs of 86 °F (30 °C) in July. The moderating influence of the ocean from the east, powered by the Gulf Stream has a strong effect on the southeastern coastal areas of the state. It also creates the potential for hurricanes near the mouth of Chesapeake Bay.[28] Although Hurricane Camille devastated Nelson County in 1969, and Fran and Isabel caused flash flooding in the mountains in 1996 and 2003, hurricanes rarely threaten communities far inland.[26][29] Thunderstorms are a regular occurrence, particularly in the western part of the state. Virginia has an annual average of 35?45 days of thunderstorm activity, and an average annual precipitation of 42.7 inches (108.5 cm).[28][30] Cold air masses arriving over the mountains, especially in winter, can lead to significant snowfalls, such as the Blizzard of 1996. The interaction of these elements with the state's topography creates distinct microclimates in the Shenandoah Valley, the mountainous southwest, and the coastal plains.[31] Virginia averages seven tornadoes annually, though most are F2 or lower on the Fujita scale.[32] In recent years, the expansion of the southern suburbs of Washington, D.C. into Northern Virginia has introduced an urban heat island primarily caused by increased absorption of solar radiation in more densely populated areas.[33] In the American Lung Association's 2009 report, 15 counties received failing grades for air quality, with Fairfax County having the worst in the state, due to automobile pollution.[34][35] Haze in the mountains is caused in part by coal power plants.[36] Forests cover 65% of the state, primarily with deciduous, broad leaf trees.[37] Lower altitudes are more likely to have small but dense stands of moisture-loving hemlocks and mosses in abundance, with hickory and oak in the Blue Ridge.[26] However since the early 1990s, Gypsy moth infestations have eroded the dominance of oak forests.[38] Other common trees and plants include chestnut, maple, tulip poplar, mountain laurel, milkweed, daisies, and many species of ferns. The largest areas of wilderness are in the western mountains and along the Atlantic coast.[39] Mammals include White-tailed deer, black bear, beaver, bobcat, coyote, raccoon, skunk, groundhog, Virginia Opossum, gray fox, and eastern cottontail rabbit.[40] Birds include cardinals, barred owls, Carolina chickadees, Red-tailed Hawks, and Wild Turkeys. The Peregrine Falcon was reintroduced into Shenandoah National Park in the mid-1990s.[41] Freshwater fish include walleye, brook trout, Roanoke bass, and blue catfish.[42] Running brooks with rocky bottoms are often inhabited by a plentiful amount of crayfish.[26] The Chesapeake Bay is home to many species, including blue crabs, clams, oysters, and rockfish (also known as striped bass).[43] Virginia has 30 National Park Service units, such as Great Falls Park and the Appalachian Trail, and one national park, the Shenandoah National Park.[44] Shenandoah was established in 1935 and encompasses the scenic Skyline Drive. Almost 40% of the park's area (79,579 acres/322 km2) has been designated as wilderness under the National Wilderness Preservation System.[45] Additionally, there are 34 Virginia state parks and 17 state forests, run by the Department of Conservation and Recreation and the Department of Forestry.[46][37] The Chesapeake Bay, while not a national park, is protected by both state and federal legislation, and the jointly run Chesapeake Bay Program which conducts restoration on the bay and its watershed. The Great Dismal Swamp National Wildlife Refuge extends into North Carolina.[47] Jamestown 2007 marked Virginia's quadricentennial year, celebrating 400 years since the establishment of the Jamestown Colony. The far-reaching social changes of the mid- to late-20th century were expressed by broad-based celebrations marking contributions of three cultures to the state: Native American, European, and African.[48][49] These three groups have each had a significant part in shaping Virginia's history. War has also had an important role, and Virginia has been a focus of warfare from the American Revolution and the Civil War to the Cold War and the War on Terrorism.[50] Myths regarding Virginia's history, such as those surrounding Pocahontas and John Smith, George Washington's childhood, or the antebellum period, have also served as rationales for the state's own ideology.[51] The first settlers arrived in Virginia about 5,000 years ago, and farming began there by 900 CE. By 1500, the Algonquian peoples had founded towns such as Werowocomoco in the Tidewater region, which they referred to as Tsenacommacah. The other major language groups in the area were the Siouan to the west, and the Iroquoians, who included the Nottoway and Meherrin, to the north and south. After 1570, the Algonquians consolidated under Chief Powhatan in response to threats from these other groups on their trade network.[52] In 1607, the native Tidewater population was between 13,000 to 14,000. Powhatan controlled more than 30 smaller tribes and over 150 settlements, who shared a common Virginia Algonquian language.[53]
