PanamaPanama (ˈpænəmɑː , pænəˈmɑː ; Panamá panaˈma), officially the Republic of Panama (República de Panamá), is a transcontinental country in Central America, spanning the southern tip of North America into the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's over million inhabitants.
Antarctic Circumpolar CurrentThe Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups (Sv, million m3/s), or possibly even higher, making it the largest ocean current. The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet.
Line IslandsThe Line Islands, Teraina Islands or Equatorial Islands (in Gilbertese, Aono Raina) are a chain of 11 atolls (with partly or fully enclosed lagoons) and coral islands (with a surrounding reef) in the central Pacific Ocean, south of the Hawaiian Islands. Eight of the atolls are parts of Kiribati. The remaining three—Jarvis Island, Kingman Reef, and Palmyra Atoll—are territories of the United States grouped with the United States Minor Outlying Islands.
AsiaAsia (ˈeɪʒə, UKalsoˈeɪʃə) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometers, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population, having more people than all other continents combined.
AcapulcoAcapulco de Juárez (akaˈpulko ðe ˈxwaɾes), commonly called Acapulco (ˌækəˈpʊlkoʊ , USalsoˌɑːk- ; Acapolco), is a city and major seaport in the state of Guerrero on the Pacific Coast of Mexico, south of Mexico City. Acapulco is located on a deep, semicircular bay and has been a port since the early colonial period of Mexico's history. It is a port of call for shipping and cruise lines running between Panama and San Francisco, California, United States. The city of Acapulco is the largest in the state, far larger than the state capital Chilpancingo.
Mariana TrenchThe Mariana Trench is an oceanic trench located in the western Pacific Ocean, about east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about in length and in width. The maximum known depth is at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. The deepest point of the trench is more than farther from sea level than the peak of Mount Everest.
Challenger DeepThe Challenger Deep is the deepest known point of the seabed of Earth. Its depth is measured at by direct measurement from deep-diving submersibles, remotely operated underwater vehicles and benthic landers, and (sometimes) slightly more by sonar bathymetry. The Challenger Deep is located in the western Pacific Ocean, at the southern end of the Mariana Trench, near the Mariana Islands. According to the August 2011 version of the GEBCO Gazetteer of Undersea Feature Names, the Challenger Deep is deep at .
Continental driftContinental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have "drifted" was first put forward by Abraham Ortelius in 1596. A pioneer of the modern view of mobilism was the Austrian geologist Otto Ampferer.
Amerigo VespucciAmerigo Vespucci (vɛˈspuːtʃi; ameˈriːɡo veˈsputtʃi; 9 March 1451 – 22 February 1512) was an Italian explorer and navigator from the Republic of Florence, from whose name the term "America" is derived. Between 1497 and 1504, Vespucci participated in at least two voyages of the Age of Discovery, first on behalf of Spain (14991500) and then for Portugal (15011502). In 1503 and 1505, two booklets were published under his name, containing colourful descriptions of these explorations and other alleged voyages.
