The Greenland ice sheet is a vast body of ice covering 660,235 sq miles, roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. Some scientists predict that climate change may be near a "tipping point" where the entire ice sheet will melt in about 2000 years. If the entire 2,850,000 cubic kilometres (683,751 cu mi) of ice were to melt, it would lead to a global sea level rise of 7.2 m (23.6 ft).

Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar.

“Maho Beach is a beach on the Dutch side of the Caribbean island of Saint Martin, in the country of Sint Maarten. It is famous for the Princess Juliana International Airport adjacent to the beach. Arriving aircraft must touch down as close as possible to the beginning of Runway 10 due to the short runway length of 2,180 metres (7,150 ft), resulting in aircraft on their final approach flying over the beach at minimal altitude”. – Wikipedia
