River Thames <=SEP=> The River Thames ( -LSB- tɛmz -RSB- ) is a river that flows through southern England , most notably through London . At 215 mi , it is the longest river entirely in England and the second longest in the United Kingdom , after the River Severn . It also flows through Oxford ( where it is called Isis ) , Reading , Henley-on-Thames and Windsor . The lower reaches of the river are called the Tideway , derived from its long tidal reach up to Teddington Lock . It rises at Thames Head in Gloucestershire , and flows into the North Sea via the Thames Estuary . The Thames drains the whole of Greater London .   Its tidal section , reaching up to Teddington Lock , includes most of its London stretch and has a rise and fall of 7 m. Running through some of the driest parts of mainland Britain and heavily abstracted for drinking water , the Thames ' discharge is low considering its length and breadth : the Severn has a discharge almost twice as large on average despite having a smaller drainage basin . In Scotland , the Tay achieves more than double the average discharge from a drainage basin that is 60 % smaller .   Along its course are 45 navigation locks with accompanying weirs . Its catchment area covers a large part of South Eastern and a small part of Western England and the river is fed by 38 named tributaries . The river contains over 80 islands . With its waters varying from freshwater to almost seawater , the Thames supports a variety of wildlife and has a number of adjoining Sites of Special Scientific Interest , with the largest being in the remaining parts of the North Kent Marshes and covering 5449 ha .   In 2010 , the Thames won the largest environmental award in the world -- the $ 350,000 International Riverprize .

Antarctica <=SEP=> Antarctica ( UK English -LSB- ænˈtɑːktɪkə -RSB- or -LSB- ænˈtɑːtɪkə -RSB- , US English -LSB- æntˈɑːrktɪkə -RSB- ) is Earth '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 14000000 km2 , 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 1.9 km in thickness , which extends to all but the northernmost reaches of the Antarctic Peninsula .   Antarctica , on average , is the coldest , driest , and windiest continent , and has the highest average elevation of all the continents . Antarctica is a desert , with annual precipitation of only 200 mm ( 8 in ) along the coast and far less inland . The temperature in Antarctica has reached − 89.2 ° C ( − 128.6 ° F ) , though the average for the third quarter ( the coldest part of the year ) is − 63 ° C ( − 81 ° F ) . Anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent . Organisms native to Antarctica include many types of algae , bacteria , fungi , plants , protista , and certain animals , such as mites , nematodes , penguins , seals and tardigrades . Vegetation , where it occurs , is tundra .   Although myths and speculation about a Terra Australis ( `` Southern Land '' ) date back to antiquity , Antarctica is noted as the last region on Earth in recorded history to be discovered and colonised by humans , being only first sighted in 1820 by the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny , who sighted the Fimbul ice shelf . The continent , however , remained largely neglected for the rest of the 19th century because of its hostile environment , lack of easily accessible resources , and isolation . In 1895 , the first confirmed landing was conducted by a team of Norwegians .   Antarctica is a de facto condominium , governed by parties to the Antarctic Treaty System that have consulting status . Twelve countries signed the Antarctic Treaty in 1959 , and thirty-eight have signed it since then . The treaty prohibits military activities and mineral mining , prohibits nuclear explosions and nuclear waste disposal , supports scientific research , and protects the continent 's ecozone . Ongoing experiments are conducted by more than 4,000 scientists from many nations .
