The Atlantic Ocean is the second-largest of the world's oceans, with an area of about 106,460,000 km2 (41,100,000 sq mi). It covers approximately 20 percent of Earth's surface and about 29 percent of its water surface area. It is known to separate the "Old World" from the "New World" in the European perception of the World.
The American Civil War was a civil war in the United States from 1861 to 1865, fought between northern states loyal to the Union and southern states that had seceded to form the Confederate States of America. The principal cause of the war was whether the enslavement of black people in the southern states should continue.
The Andes, Andes Mountains or Andean Mountains are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 7,000 km (4,350 mi) long, 200 to 700 km wide, and has an average height of about 4,000 m (13,123 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
The Confederate States of America (CSA), commonly referred to as the Confederate States or the Confederacy, was an unrecognized breakaway state in existence from February 8, 1861, to May 9, 1865, that fought against the United States of America during the American Civil War. The eleven states that seceded from the Union and formed the main part of the CSA were South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina.
The jaguar is a large felid species and the only living member of the genus Panthera native to the Americas. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to darker rosettes on the sides. With a body length of up to 1.85 m, it is the largest cat species in the New World and the third largest in the world. Its powerful bite allows it to pierce the shells of armored reptiles and to employ an unusual killing method with mammals: it bites directly through the skull of prey between the ears to deliver a fatal blow to the brain.
March is the third month of the year and named after Mars in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March.
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Well-known marsupials include kangaroos, wallabies, koalas, opossums, wombats, Tasmanian devils, and the extinct thylacine. Some lesser-known marsupials are the dunnarts, potoroos, and the cuscus.
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be described as a southern subcontinent of the Americas. The reference to South America instead of other regions has increased in recent decades due to changing geopolitical dynamics.
The Americas is a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World.
The Vietnam War, also known as the Second Indochina War, and in Vietnam as the Resistance War Against America or simply the American War, was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. North Vietnam was supported by the Soviet Union, China, and other communist allies; South Vietnam was supported by the United States, South Korea, the Philippines, Australia, Thailand, and other anti-communist allies. The war, considered a Cold War-era proxy war by some, lasted 19 years, with direct U.S. involvement ending in 1973, and included the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist in 1975.
The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west.
The Army of the Republic of Vietnam were the ground forces of the South Vietnamese military from its inception in 1955 to the Fall of Saigon in April 1975. It is estimated to have suffered 1,394,000 casualties during the Vietnam War.
The Eastern Standard Time Zone (EST) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama and Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands.
In geology and physical geography, a plateau, also called a high plain or a tableland, is an area of a highland consisting of flat terrain, that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones.
The United States of America (USA), commonly known as the United States or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major self-governing territories, 326 Indian reservations, and some minor possessions. At 3.8 million square miles, it is the world's third- or fourth-largest country by total area. With a population of more than 328 million people, it is the third most populous country in the world. The national capital is Washington, D.C., and the most populous city is New York City.
Gondwana or Gondwanaland was a supercontinent that existed from the Neoproterozoic and began to break up during the Jurassic, with the opening of the Drake Passage, separating South America and Antarctica occurring during the Eocene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it.
Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States. These laws were enacted in the late 19th and early 20th centuries by white Southern Democrat-dominated state legislatures to disenfranchise and remove political and economic gains made by black people during the Reconstruction period. The Republican Party lily-white movement supported the exclusion of African Americans. The Jim Crow laws were enforced until 1965.
A continent is one of several large landmasses. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Variations with fewer continents may merge some of these, for example some systems include Eurasia or America as single continents.
Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and began to break apart about 175 million years ago. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the Equator and surrounded by the superocean Panthalassa. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
The South American U18 Championships in Athletics is a biennial athletics event organized by "Confederación Sudamericana de Atletismo" (CONSUDATLE), the South American area association of the International Amateur Athletic Federation (IAAF). Starting in 1973, the competition was open for athletes under-17 in the early years. Since 2000 the international age group definition has applied. Up until the 2016 edition the competition was known as the South American Youth Championships in Athletics. The tournament is open for athletes from CONSUDATLE member federations. Athletes from IAAF members of other geographical areas may be invited. However, they are not considered in the classification.
