National Geographic World Championship: The National Geographic World Championship (previously called the International Geography Olympiad, which is now the title of another similar competition for older schoolchildren) is a biennial, two-day-long international geography competition typically held in late July or early August.  The Championship was first held in 1993, and is sponsored by the National Geographic Society.  Teams of three students plus one alternate are selected from among those who finished highest in their respective countries' national competitions (e.g. the National Geographic Bee in the U.S.A., the Olimpíada Geográfica Argentina in Argentina or the Australian Geography Competition in Australia).  On the first day of competition, these teams take a written test on which all members confer and work together, then take part in a team geography skills-testing activity, such as using a map to find specified locations in unfamiliar surroundings.  The scores from these two events are tallied, and the top three teams advance to the final round on the second day.  The final round consists of questions primarily in the style of the National Geographic Bee, as a moderator (since 1993, Alex Trebek) reads questions to one team or one individual at a time.  These questions may also involve the use of visual aids such as maps or photographs.  Members of the top three teams receive bronze, silver, or gold medals for finishing third, second, or first, respectively.
