The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained in areas where wood is not readily available. Though it was used historically as a domestic fuel, coal is now used mostly in industry, especially in smelting and alloyproduction as well as electricity generation. Large-scale coal mining developed during the Industrial Revolution, and coal provided the main source of primary energy for industry and transportation in industrial areas from the 18th century to the 1950s. Coal remains an important energy source because of its low cost and abundance compared to other fuels, particularly for electricity generation.[1] Coal is also mined today on a large scale by open pit methods wherever the coal strata strike the surface or are relatively shallow. Britain developed the main techniques of underground coal mining from the late 18th century onward, with further progress being driven by 19th century and early 20th century progress.[1] However, oil and gas were increasingly used as alternatives from the 1860s onward.
By the late 20th century, coal was, for the most part, replaced in domestic as well as industrial and transportation usage by oil, natural gas or electricity produced from oil, gas, nuclear power or renewable energysources. By 2010, coal produced over a fourth of the world's energy, and by 2050 it is expected to produce about a third.[2]
Since 1890, coal mining has also been a political and social issue. Coal miners' labour and trade unions became powerful in many countries in the 20th century, and often, the miners were leaders of the Left or Socialist movements (as in Britain, Germany, Poland, Japan, Chile, Canada and the U.S.)[3][4] Since 1970, environmental issueshave been increasingly important, including the health of miners, destruction of the landscape from strip mines and mountaintop removal, air pollution, and coal combustion's contribution to global warming.
The coal deposits of Appalachia (That Region) were formed in the time of the dinosaurs because perfect conditions were there. The conditions are warm, wet, and muddy.

The pilgrims landed in Plymouth, Massachusetts instead of Virginia.
Virginia voted to secede on Apr. 17, 1861. The secession vote was ratified by the citizens of Virginia on May 23. Virginia then existed as an independent republic until it joined the Confederacy on June. 19, 1861.
{| |- | The North wasn't 'formed.' It already existed as the United States of America. The states included Maine, New Hampshire, New York, Vermont, Pennsylvania, New Jersey, Ohio, Michigan, Indiana, Wisconsin, Maryland, Connecticut, Massachusetts and later on West Virginia. |}
None. Pennsylvania was a place long before humans even existed. It was also home to thousands of Native Americans before the arrival of Europeans in the 17th century.
Virgina did have volcanoes in the ancient times. Scientists have found traces of volcanic rock in the ground.

East Virginia- - - - There is a Virginia that was one of the original colonies and is still a state. In 1863 the state of WEST VIRGINIA split away from Virginia because Virginia was trying to split away from the United States back in the Civil War. Virginia approved of slavery, West Virginia's people did not approve of slavery and they broke away from Virginia during the civil war. But As far as an East Virginia - it does not exist - it has never existed, unless you asked the question for a joke perhaps? Mike - from Wheeling West Virginia
