Sinkholes[edit | edit source]

  • sinkholes are holes or caves in the ground caused by erosion or a collapse of a lower, below-ground surface, usually because of water drainage
  • sinkholes may also be caused by a drainage of water, such as a water table decline
  • sinkholes are most common where limestone, sandstone, salt beds, or gypsum are prevalent
Thor's Well: a sinkhole on the coast of Cape Perpetua, Oregon

  • see: https://en.wikipedia.org/wiki/Enclave_and_exclave

      • Brunei (surrounded by the Malaysian state, Sarawak, and the South China Sea)

  • exclave = a territory or part of a country that is separated from the main country or territory
  • examples

Geographic extremes[edit | edit source]

Largest & smallest nations, Highest & lowest populations[edit | edit source]

Africa

  • Algeria is the largest country in Africa
  • The Gambia is the smallest country in mainland Africa
    • The Gambia is a semi-enclave surrounded by Senegal and the Atlantic Ocean
  • Seychelles is the smallest country in Africa, including islands
  • Nigeria has the highest population in Africa
    • Ethiopia as the 2nd highest population
  • Djibouti has the lowest population in mainland Africa
  • Seychelles has the lowest population in Africa among independent nations (territories excluded) and including island states

    • Seychelles has the second lowest population in Africa, including island states and territories

Asia

Australia

  • Australia is the largest and the smallest country in Australia
    • Australia is the only country to entirely occupy a continent

Directional extremes (north, south, east, west)[edit | edit source]

United States

Extreme points in the contiguous 48 states: Northwest Angle (MN), Ballast Key (FL), Sail Rock (ME), Bodelteh Islands (WA) See https://en.wikipedia.org/wiki/List_of_extreme_points_of_the_United_States
  • northernmost state in the continental U.S.: Minnesota
  • northernmost point in the continental U.S.: Northwest Angle, Minnesota, known as "The Angle"
    • when negotiating the US-Canadian border following the American Revolution (Treaty of Paris, 1783), negotiators used an inaccurate map of the border of present-day Minnesota and Canada, and thereby included the northwest portion of the Lake of the Woods as the border, while it actually lies within Canadian territory
    • thus The Angle is one of six "practical exclaves" of the U.S., as it is only accessible by land via Canada
    • in 2010, it's population was 119
    • see: Northwest Angle (wiki)
