Mount Erebus is the second - highest volcano in Antarctica ( after Mount Sidley ) and the southernmost active volcano on ___MASK42___ . It is the sixth highest ultra mountain on an island . With a summit elevation of , it is located on Ross Island , which is also home to three inactive volcanoes , Mount Terror , Mount Bird , and Mount Terra Nova . Sydenham is a suburban district of south - east ___MASK70___ in the ___MASK70___ Boroughs of Lewisham , Bromley and Southwark . Located in Kent until 1889 , when the County of ___MASK70___ was created , Sydenham was historically a very affluent town and the Crystal Palace from the Great Exhibition was relocated to Sydenham Hill in 1854 . Bordering Forest Hill , Dulwich , Crystal Palace , Penge , Beckenham , Catford and Bellingham ; Sydenham today is a diverse area with a 2011 population of 28 , 378 . Athy is a market town at the meeting of the River Barrow and the Grand Canal in south - west County Kildare , ___MASK58___ , 72 kilometres southwest of Dublin . In geography , latitude is a geographic coordinate that specifies the north  south position of a point on the ___MASK42___ ' s surface . Latitude is an angle ( defined below ) which ranges from 0 ° at the Equator to 90 ° ( North or South ) at the poles . Lines of constant latitude , or parallels , run east  west as circles parallel to the equator . Latitude is used together with longitude to specify the precise location of features on the surface of the ___MASK42___ . Approximations employed . Two levels of abstraction are employed in the definition of these coordinates . In the first step the physical surface is modelled by the geoid , a surface which approximates the mean sea level over the oceans and its continuation under the land masses . The second step is to approximate the geoid by a mathematically simpler reference surface . The simplest choice for the reference surface is a sphere , but the geoid is more accurately modelled by an ellipsoid . The definitions of latitude and longitude on such reference surfaces are detailed in the following sections . Lines of constant latitude and longitude together constitute a graticule on the reference surface . The latitude of a point on the " actual " surface is that of the corresponding point on the reference surface , the correspondence being along the normal to the reference surface which passes through the point on the physical surface . Latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO 19111 standard . ___MASK42___ , otherwise known as the world , is the third planet from the Sun and the only object in the Universe known to harbor life . It is the densest planet in the Solar System and the largest of the four terrestrial planets . A continent is one of several very large landmasses on ___MASK42___ . Generally identified by convention rather than any strict criteria , up to seven regions are commonly regarded as continents . Ordered from largest in size to smallest , they are : Asia , Africa , North America , South America , Antarctica , Europe , and Australia . In geology , areas of continental crust include regions covered with water . Sir Ernest Henry Shackleton ( 15 February 1874  5 January 1922 ) was a polar explorer who led three ___MASK71___ expeditions to the Antarctic , and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration . Born in Kilkea , Athy , County Kildare , Ireland , Shackleton and his Anglo - Irish family moved to Sydenham in suburban south London when he was ten . His first experience of the polar regions was as third officer on Captain Robert Falcon Scott ' s Discovery Expedition 1901  1904 , from which he was sent home early on health grounds , after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82 ° S . Captain Robert Falcon Scott , ( 6 June 1868  29 March 1912 ) was a ___MASK71___ Royal Navy officer and explorer who led two expeditions to the Antarctic regions : the Discovery Expedition , 1901  1904 , and the ill - fated Terra Nova Expedition , 1910  1913 . On the first expedition , he set a new southern record by marching to latitude 82 ° S and discovered the Polar Plateau , on which the South Pole is located . During the second venture , Scott led a party of five which reached the South Pole on 17 January 1912 , four weeks after Roald Amundsen ' s Norwegian expedition . On their return journey , Scott ' s party discovered plant fossils , proving Antarctica was once forested and joined to other continents . A planned meeting with supporting dog teams from the base camp failed , despite Scott ' s written instructions , and at a distance of 150 miles from their base camp and 11 miles from the next depot , Scott and his companions perished . The ___MASK71___ Antarctic Expedition 1907  09 , otherwise known as the Nimrod Expedition , was the first of three expeditions to the Antarctic led by Ernest Shackleton . Its main target , among a range of geographical and scientific objectives , was to be first to the South Pole . This was not attained , but the expedition ' s southern march reached a Farthest South latitude of 88 ° 23 ' S , just from the pole . This was by far the longest southern polar journey to that date and a record convergence on either Pole . A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South Magnetic Pole , and the expedition also achieved the first ascent of Mount Erebus , Antarctica ' s second highest volcano . Kilkea ( meaning " church of Cathac "), ( pop 92 ) is a village in County Kildare , ___MASK58___ , about from Dublin , and from the town of Carlow . The R418 regional road from Athy to Tullow passes through the village . ___MASK33___ , officially the Commonwealth of ___MASK33___ , is a country comprising the mainland of the Australian continent , the island of Tasmania and numerous smaller islands . It is the world ' s sixth - largest country by total area . The neighbouring countries are ___MASK69___ , ___MASK67___ and East Timor to the north ; the Solomon Islands and Vanuatu to the north - east ; and ___MASK6___ to the south - east . ___MASK33___ ' s capital is Canberra , and its largest urban area is Sydney . ___MASK58___ ( Ulster - Scots : ) is an island in the North Atlantic . It is separated from ___MASK37___ to its east by the North Channel , the Irish Sea , and St George ' s Channel . ___MASK58___ is the second - largest island of the ___MASK71___ Isles , the third - largest in Europe , and the twentieth - largest on ___MASK42___ . The Antarctic ( US English , UK English or and or ) is a polar region , specifically the region around the ___MASK42___ ' s South Pole , opposite the Arctic region around the North Pole . The Antarctic comprises in the strict sense the continent of Antarctica and the island territories located on the Antarctic Plate . In a broader sense the Antarctic region include the ice shelves , waters , and island territories in the Southern Ocean situated south of the Antarctic Convergence , a zone approximately wide varying in latitude seasonally . The region covers some 20 % of the Southern Hemisphere , of which 5 . 5 % ( 14 million km ) is the surface area of the Antarctic continent itself . All of the land and ice shelves south of 60 ° S latitude are administrated under the Antarctic Treaty System . In a biogeographic sense , the Antarctic ecozone is one of eight ecozones of the ___MASK42___ ' s land surface . The Southern Ocean , also known as the Antarctic Ocean or the ___MASK23___ Ocean , comprises the southernmost waters of the World Ocean , generally taken to be south of 60 ° S latitude and encircling Antarctica . As such , it is regarded as the fourth - largest of the five principal oceanic divisions : smaller than the Pacific , Atlantic , and Indian Oceans but larger than the Arctic Ocean . This ocean zone is where cold , northward flowing waters from the Antarctic mix with warmer subantarctic waters . The ___MASK71___ National Antarctic Expedition , 1901  04 , generally known as the " Discovery " Expedition , was the first official ___MASK71___ exploration of the Antarctic regions since James Clark Ross ' s voyage sixty years earlier . Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society ( RGS ), the new expedition aimed to carry out scientific research and geographical exploration in what was then largely an untouched continent . It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration , including Robert Falcon Scott who led the expedition , Ernest Shackleton , Edward Wilson , Frank Wild , Tom Crean and William Lashly . Antarctica ( US English , UK English or ) is ___MASK42___ ' s southernmost continent . It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere , almost entirely south of the Antarctic Circle , and is surrounded by the Southern Ocean . At , it is the fifth - largest continent . For comparison , Antarctica is nearly twice the size of Australia . About 98 % of Antarctica is covered by ice that averages in thickness , which extends to all but the northernmost reaches of the Antarctic Peninsula . The South Pole , also known as the Geographic South Pole or Terrestrial South Pole , is one of the two points where the ___MASK42___ ' s axis of rotation intersects its surface . It is the southernmost point on the surface of the ___MASK42___ and lies on the opposite side of the ___MASK42___ from the North Pole . County Kildare is a county in ___MASK58___ . It is located in the province of Leinster and is part of the Mid - East Region . It is named after the town of Kildare . Kildare County Council is the local authority for the county which has a population of 222 , 130 . George Buckley ( 1866 -- 1937 ) explored Antarctica with the Nimrod Expedition led by Ernest Shackleton . The Heroic Age of Antarctic Exploration was an era beginning at the end of the 19th century and closing with Shackleton ' s Imperial Trans - Antarctic Expedition , the survivors stepping ashore in Wellington , ___MASK6___ February 9 , 1917 . Historian Aant Elzinga gives the much later date of 1945 , considering World War II to be the turning point in Antarctic research . During this period the Antarctic continent became the focus of an international effort that resulted in intensive scientific and geographical exploration and in which 17 major Antarctic expeditions were launched from ten countries . The common factor in these expeditions was the limited nature of the resources available to them before advances in transport and communication technologies revolutionized the work of exploration . This meant that each expedition became a feat of endurance that tested , and sometimes exceeded its personnel ' s physical and mental limits . The " heroic " label , bestowed later , recognized the adversities which had to be overcome by these pioneers , some of whom did not survive the experience ; during this period 19 expedition members died . The Southern Hemisphere is the half sphere of ___MASK42___ which is south of the equator . It contains all or parts of five continents ( Antarctica , Australia , about 90 % of South America , the southern third of Africa , and several southern islands off the continental mainland of Asia ), four oceans ( Indian , South Atlantic , Southern , and South Pacific ) and most of the Pacific Islands in Oceania . Its surface is 80 . 9 % water , compared with 60 . 7 % water in the case of the Northern Hemisphere , and it contains 32 . 7 % of ___MASK42___ ' s land . Sir Tannatt William Edgeworth David ( 28 January 1858  28 August 1934 ), professionally known as Edgeworth David , was a Welsh Australian geologist and Antarctic explorer . A household name in his lifetime , David ' s most significant achievements were discovering the major Hunter Valley coalfield in New South ___MASK4___ and leading the first expedition to reach the South Magnetic Pole . He also served with distinction in World War I .
