Divergent boundary
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Bikini
While the two - piece swimsuit as a design existed in classical antiquity, the modern design first attracted public notice in Paris on July 5, 1946. French automotive engineer Louis Réard introduced a design he named the ``bikini '', adopting the name from the Bikini Atoll in the Pacific Ocean, which was the colonial name the Germans gave to the atoll, transliterated from the Marshallese name for the island, Pikinni.
Elephant Island
Elephant Island is an ice-covered mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. Its name was possibly given by early explorers sighting elephant seals on its shores. The island is situated north-northeast of the tip of the Antarctic Peninsula, west-southwest of South Georgia, south of the Falkland Islands, and southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the UK. Brazil has a shelter on the island, Goeldi, supporting the work of up to six researchers each during the summer and had another (Wiltgen), which was dismantled in the summer of 1997/98.

Moutonnée Valley
Moutonnée Valley is a valley in the Ganymede Heights area on the east coast of Alexander Island, Antarctica. The valley runs eastward towards Moutonnée Lake and George VI Sound. It was named in association with the lake by the United Kingdom Antarctic Place-Names Committee in 1980. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Dos Rios AVA
The Dos Rios AVA is an American Viticultural Area located in northern Mendocino County, California. The appellation is located near the confluence of the Eel River and the Middle Fork of the Eel River. The name of the appellation is Spanish for "two rivers". The location would have a warm climate if not for constant breezes from the Pacific Ocean. The soil in Dos Rios is more infertile than other regions in the county. Only one winery, Vin de Tevis, currently operates within the boundaries of the AVA.
Strome, Alberta
Strome is a hamlet in east-central Alberta, Canada within Flagstaff County. It is located on Highway 13, approximately east of the City of Camrose. The hamlet was originally incorporated as a village on February 3, 1910. It dissolved to become a hamlet under the jurisdiction of Flagstaff County on January 1, 2016. Strome's name is believed to come from Stromeferry in Ross & Cromarty, Scotland.
Antarctica
Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Eltanin Bay
Eltanin Bay is a bay in Antarctica about wide in the southern Bellingshausen Sea that indents the coast of Ellsworth Land west of the Wirth Peninsula. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–66, and was named by the Advisory Committee on Antarctic Names for the United States Antarctic Research Program oceanographic research ship "Eltanin" which made numerous research cruises in the South Pacific Ocean.
Circle of Animals/Zodiac Heads
Circle of Animals/Zodiac Heads is an artwork by Chinese contemporary artist and political commentator, Ai Weiwei. The work comes in a small (gold) and large (bronze) version.
Antarctica
Small-scale "expedition tourism" has existed since 1957 and is currently subject to Antarctic Treaty and Environmental Protocol provisions, but in effect self-regulated by the International Association of Antarctica Tour Operators (IAATO). Not all vessels associated with Antarctic tourism are members of IAATO, but IAATO members account for 95% of the tourist activity. Travel is largely by small or medium ship, focusing on specific scenic locations with accessible concentrations of iconic wildlife. A total of 37,506 tourists visited during the 2006–07 Austral summer with nearly all of them coming from commercial ships. The number was predicted to increase to over 80,000 by 2010.
Water distribution on Earth
Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 78% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot. An estimated 1.5 to 11 times the amount of water in the oceans may be found hundreds of miles deep within the Earth's interior, although not in liquid form.
Cedar Beach, New Jersey
Cedar Beach is an unincorporated community within Berkeley Township, in Ocean County, New Jersey, United States. It is situated on Barnegat Bay and located east of U.S. Route 9.
HMS Scott (H131)
HMS "Scott" is an ocean survey vessel of the Royal Navy, and the only vessel of her class. She is the third Royal Navy ship to carry the name, and the second to be named after the Antarctic explorer, Robert Falcon Scott. She was ordered to replace the survey ship .
Bird migration
The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of tubenoses (Procellariiformes) such as albatrosses circle the earth, flying over the southern oceans, while others such as Manx shearwaters migrate 14,000 km (8,700 mi) between their northern breeding grounds and the southern ocean. Shorter migrations are common, including altitudinal migrations on mountains such as the Andes and Himalayas.
Southern Ocean
The Southern Ocean, geologically the youngest of the oceans, was formed when Antarctica and South America moved apart, opening the Drake Passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar Current.
Kingdom of Württemberg
The Kingdom of Württemberg ( ) was a German state that existed from 1805 to 1918, located within the area that is now Baden-Württemberg. The kingdom was a continuation of the Duchy of Württemberg, which existed from 1495 to 1805.
Winter Quarters Bay
Winter Quarters Bay is a small cove of McMurdo Sound, Antarctica, located due south of New Zealand at 77°50'S. The harbor is the southern-most port in the Southern Ocean and features a floating ice pier for summer cargo operations. The bay is approximately 250m wide and long, with a maximum depth of 33m. The name Winter Quarters Bay refers to Robert Falcon Scott's National Antarctic Discovery Expedition (1901–04) which wintered at the site for two seasons.
Harneys Corner, New Jersey
Harneys Corner is an unincorporated community located within Lawrence Township in Mercer County, New Jersey, United States. It is located at the intersection of Lawrence Road (U.S. Route 206) and Princeton Pike / Avenue (County Route 583). Located in the southern portion of the township close to the Trenton and Ewing borders, the area consists of small houses on nearby side streets and businesses along the aforementioned arterial roads. The intersection itself is located about north of the Brunswick Circle.
Northern Hemisphere
The Arctic is the region north of the Arctic Circle. Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic experiences some days in summer when the Sun never sets, and some days during the winter when it never rises. The duration of these phases varies from one day for locations right on the Arctic Circle to several months near the North Pole, which is the middle of the Northern Hemisphere.
