The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about 106,460,000 km2 (41,100,000 sq mi). It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World.
The Amazon River in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile.
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory.
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.
High-speed rail (HSR) is a type of rail system that runs significantly faster than traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines in excess of 200 km/h (124 mph) are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964 and was widely known as the bullet train.
Sakha, officially the Republic of Sakha (Yakutia), is a republic of Russia, in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million. Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers. Yakutsk, which is the world's coldest major city, is its capital and largest city. The republic has a reputation for an extreme and severe climate, with the lowest temperatures in the Northern Hemisphere being recorded in Verkhoyansk and Oymyakon, and regular winter averages commonly dipping below −35 °C (−31 °F) in Yakutsk. The hypercontinental tendencies also result in warm summers for much of the republic.
Kauaʻi, anglicized as Kauai, is geologically the second-oldest of the main Hawaiian Islands. With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of these islands and the 21st largest island in the United States. Known also as the "Garden Isle", Kauaʻi lies 73 miles (117 km) across the Kauaʻi Channel, northwest of Oʻahu. This island is the site of Waimea Canyon State Park and the Na Pali Coast State Park.
The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies.
The Brahmaputra, also known as the Yarlung Tsangpo in Tibet, the Siang/Dihang River in Arunachal Pradesh, and Luit in Assamese, is a trans-boundary river which flows through Tibet, India, and Bangladesh. It is the 9th largest river in the world by discharge, and the 15th longest.
The atmosphere of Earth or air is the layer of gases retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention, and reducing temperature extremes between day and night.
The World Athletics Championships are a biennial athletics competition organized by World Athletics. Alongside the Olympic Games, they represent the highest level championships of senior international outdoor athletics competition for track and field athletics globally, including marathon running and race walking. Separate World Championships are held by World Athletics for certain other outdoor events, including cross-country running and half-marathon, as well as indoor and age-group championships.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea out to 200 nautical miles (nmi) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea. The surface waters, as can be seen in the map, are international waters.
Racewalking, or race walking, is a long-distance discipline within the sport of athletics. Although a foot race, it is different from running in that one foot must appear to be in contact with the ground at all times. Race judges carefully assess that this is maintained throughout the race. Typically held on either roads or running tracks, common distances range from 3,000 metres (1.9 mi) up to 100 kilometres (62.1 mi).
The Autobahn is the federal controlled-access highway system in Germany. The official German term is Bundesautobahn, which translates as 'federal motorway'. The literal meaning of the word Bundesautobahn is 'Federal Auto(mobile) Track'.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, expressway and speedway. Other similar terms include throughway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers 143,550 sq mi (372,000 km2) and a volume of 78,200 km3 (19,000 cu mi). It has a salinity of approximately 1.2%, about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast.
The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Southeastern Europe, from the Black Forest into the Black Sea. Its longest headstream Breg rises in Furtwangen im Schwarzwald, while the river carries its name from its source confluence in Donaueschingen onwards.
