Provinces of Virginia
The provinces of VA are divided by geology & geography. They are an extension of the Physiography of North America
1.Pacific Coastal Plain 2.Southwest 3.Rocky Mountains 4.Great Plains 5.Central Lowlands 6.Appalachian & Ozark Plateaus 7.Gulf & Atlantic Coastal Plain 8.Canadian Shield
Coastal Plain (Tidewater) Eastern most province. Flat Land w/ lots of wetlands & marshes Part of Atlantic Coast of U.S.A. Sand, gravel & clay are quarried (construction aggregate) a component of composite materials such as concrete and asphalt. are widely used in drainage applications like septic fields. are also used as base material under foundations, roads, and railroads.
Fall Line: The natural border between the Coastal Plain & the Piedmont. Has many waterfalls & rapids (whitewater) Location of major cities
Piedmont Piedmont means “foot of the Mountains” Foothills of the Appalachians Rolling hills that get steeper as you go west. Kyanite, slate, vermiculite, granite, gabbro, diabase, and feldspar are quarried here. (mostly for aggregate)
Blue Ridge Old (250 million years old), rounded mountains. Part of the Appalachian Mountain Range. Source of many rivers in Virginia. Blue Ridge rocks are quarried for quartzite as crushed stone and, in the past, mining occurred for copper, iron, & manganese.
Valley & Ridge Part of the Appalachian Mountain Range Includes the Great Valley of Virginia West of Blue Ridge Mountains Resources currently extracted from this province are limestone, dolomite, sandstone, gypsum, iron oxides, clay, oil, natural gas, and shale.
Appalachian Plateau Smallest province (only 3 counties) A Plateau is elevated like a mountain, but flat on top. In addition to COAL, this province contains methane (CH 4 ) or natural gas.
