Amelia Courthouse, Virginia
Amelia Court House (also known as Amelia Courthouse and Amelia) is the county seat of Amelia County in the U.S. state of Virginia and a census-designated place (CDP). The population as of the 2010 census was 1,099. The town was named for Princess Amelia of Great Britain, the daughter of Great Britain's King George II, in 1735. History Amelia Court House was founded in a rural area of the Virginia Piedmont developed for plantations of mixed crops. In the 19th century, spas were developed around nearby mineral springs, which served as vacation destinations for travelers. Visitors arrived by railroad after one was built to serve the area. Among the planters who came to the spas with their families was Robert E. Lee, the future Confederate general. By the 1860s, the village was served by the Richmond and Danville Railroad (later the Southern Railway). The R&D was a crucial supply line for the Confederacy during the Civil War. After General Robert E. Lee retreated from Petersbur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Census-designated Place
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities, colonias located along the Mexico–United States border, and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unin ...

Humid Subtropical Climate
A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification was officially created under the Trewartha climate classification. In this classification, climates are termed humid subtropical when the ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feldspar
Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight. Feldspars crystalize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Compositions The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: * potassium feldspar (K-spar) ...

Microcline
Microcline (KAlSi3O8) is an important igneous rock-forming tectosilicate mineral. It is a potassium-rich alkali feldspar. Microcline typically contains minor amounts of sodium. It is common in granite and pegmatites. Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase. Sanidine is a polymorph of alkali feldspar stable at yet higher temperature. Microcline may be clear, white, pale-yellow, brick-red, or green; it is generally characterized by cross-hatch twinning that forms as a result of the transformation of monoclinic orthoclase into triclinic microcline. The chemical compound name is potassium aluminium silicate, and it is known as E number reference E555. Geology Microcline may be chemically the same as monoclinic orthoclase, but because it belongs to the triclinic crystal system, the prism angle is slightly less than right angles; hence the name "microcline" from the Greek "small slope." It is a fully ordered triclin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazonite
Amazonite, also known as Amazonstone, is a green tectosilicate mineral, a variety of the potassium feldspar called microcline. Its chemical formula is KAlSi3O8, which is polymorphic to orthoclase. Its name is taken from that of the Amazon River, from which green stones were formerly obtained, though it is unknown whether those stones were amazonite. Although it has been used for over two thousand years, as attested by archaeological finds in Egypt and Mesopotamia, no ancient or medieval authority mentions it. It was first described as a distinct mineral only in the 18th century.Mikhail Ostrooumov, ''Amazonite: Mineralogy, Crystal Chemistry, and Typomorphism'' (Elsevier, 2016), p. 1-12. Green and greenish-blue varieties of potassium feldspars that are predominantly triclinic are designated as amazonite. It has been described as a "beautiful crystallized variety of a bright verdigris-green" and as possessing a "lively green colour." It is occasionally cut and used as a gemstone. ...

Army Of Northern Virginia
The Army of Northern Virginia was the primary military force of the Confederate States of America in the Eastern Theater of the American Civil War. It was also the primary command structure of the Department of Northern Virginia. It was most often arrayed against the Union Army of the Potomac. Origin The name ''Army of Northern Virginia'' referred to its primary area of operation, as did most Confederate States Army names. The Army originated as the Army of the Potomac, which was organized on June 20, 1861, from all operational forces in northern Virginia. On July 20 and July 21, the Army of the Shenandoah and forces from the District of Harpers Ferry were added. Units from the Army of the Northwest were merged into the Army of the Potomac between March 14 and May 17, 1862. The Army of the Potomac was renamed ''Army of Northern Virginia'' on March 14. The Army of the Peninsula was merged into it on April 12, 1862.Eicher, pp. 889–90. Robert E. Lee's biographer, Douglas S. ...

Appomattox Court House National Historical Park
The Appomattox Court House National Historical Park is a preserved 19th-century village in Appomattox County, Virginia. The village is famous for the site of the Battle of Appomattox Court House, and contains the house of Wilmer McLean, where the surrender of the Army of Northern Virginia under Robert E. Lee to Union commander Ulysses S. Grant took place on April 9, 1865, effectively ending the American Civil War. The McLean House was the site of the surrender conference, but the village itself was named for the presence nearby of what is now preserved as the Old Appomattox Court House. The park was established in 1935. The village was made a national monument in 1940 and a national historical park in 1954. It is located about east of Appomattox, Virginia, the location of the Appomattox Station and the "new" Appomattox Court House. It is in the center of the state about east of Lynchburg, Virginia. The park has a couple of dozen restored buildings, a few ruins, and some ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Sayler's Creek
The Battle of Sailor's Creek was fought on April 6, 1865, near Farmville, Virginia, as part of the Appomattox Campaign, near the end of the American Civil War. It was the last major engagement between the Confederate Army of Northern Virginia, commanded by General Robert E. Lee and the Army of the Potomac, under the overall direction of Union General-in-Chief Lieutenant General Ulysses S. Grant. After abandoning Petersburg, the exhausted and starving Confederates headed west, hoping to re-supply at Danville or Lynchburg, before joining General Joseph E. Johnston in North Carolina. But the stronger Union army kept pace with them, exploiting the rough terrain full of creeks and high bluffs, where the Confederates’ long wagon trains were highly vulnerable. The two small bridges over Sailor's Creek and Little Sailor's Creek caused a bottleneck that further delayed the Confederates’ attempt to escape. After some desperate hand-to-hand fighting, about a quarter of the remaining e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Army
During the American Civil War, the Union Army, also known as the Federal Army and the Northern Army, referring to the United States Army, was the land force that fought to preserve the Union (American Civil War), Union of the collective U.S. state, states. It proved essential to the preservation of the United States as a working, viable republic. The Union Army was made up of the permanent Regular Army (United States), regular army of the United States, but further fortified, augmented, and strengthened by the many temporary units of dedicated United States Volunteers, volunteers, as well as including those who were drafted in to service as Conscription in the United States, conscripts. To this end, the Union Army fought and ultimately triumphed over the efforts of the Confederate States Army in the American Civil War. Over the course of the war, 2,128,948 men enlisted in the Union Army, including 178,895 United States Colored Troops, colored troops; 25% of the white men who s ...
