An iceberg is a large piece of ice from freshwater that has broken off from a snow-formed glacier or ice shelf and is floating in open water. It may subsequently become frozen into pack ice. Alternatively, it may come to rest on the seabed in shallower water, causing ice scour (also known as ice gouging) or becoming an ice island.
The word "iceberg" is a partial loan translation from Dutch ijsberg, literally meaning ice mountain, cognate to Danish Isbjerg, German Eisberg, Low Saxon Iesbarg and Swedish Isberg.
Because the density of pure ice is about 920 kg/m³, and that of sea water about 1025 kg/m³, typically only one-ninth of the volume of an iceberg is above water. The shape of the underwater portion can be difficult to judge by looking at the portion above the surface. This has led to the expression "tip of the iceberg", for a problem or difficulty that is only a small manifestation of a larger problem.
Icebergs generally range from 1 to 75 metres (3.3 to 246 ft) above sea level and weigh 100,000 to 200,000 metric tons (110,000 to 220,000 short tons). The largest known iceberg in the North Atlantic was 168 metres (551 ft) above sea level, reported by the USCG icebreaker East Wind in 1958, making it the height of a 55-storey building. These icebergs originate from the glaciers of western Greenland, and may have an interior temperature of -15 to -20 °C (5 to -4 °F).
Though usually confined by winds and currents to move close to the coast, the largest icebergs recorded have been calved, or broken off, from the Ross Ice Shelf of Antarctica. Iceberg B-15, photographed by satellite in 2000, measured 295 by 37 kilometres (183 by 23 mi), with a surface area of 11,000 square kilometres (4,200 sq mi). The mass was estimated around three billion tonnes. The largest iceberg on record was an Antarctic tabular iceberg of over 31,000 square kilometres (12,000 sq mi) [335 by 97 kilometres (208 by 60 mi)] sighted 150 miles (240 km) west of Scott Island, in the South Pacific Ocean, by the USS Glacier on November 12, 1956. This iceberg was larger than Belgium.
When an iceberg melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when compressed air bubbles trapped in the iceberg pop. The bubbles come from air trapped in snow layers that later became glacial ice.

The Republic of Cuba (pronounced /ˈkjuːbə/ ( listen); Spanish: República de Cuba, pronounced [reˈpuβlika ðe ˈkuβa] ( listen)) is an island nation in the Caribbean. The nation of Cuba consists of the main island of Cuba, the Isla de la Juventud, and several archipelagos. Havana is the largest city in Cuba and the country's capital. Santiago de Cuba is the second largest city. To the north of Cuba lies the United States and the Bahamas, Mexico is to the west, the Cayman Islands and Jamaica are to the south, and Haiti and the Dominican Republic are to the southeast.
In 1492, Christopher Columbus found and claimed the island now occupied by Cuba, for the Kingdom of Spain. Cuba remained a territory of Spain until the Spanish–American War ended in 1898, and gained formal independence from the U.S. in 1902. Between 1953 and 1959 the Cuban Revolution occurred, removing the dictatorship of Fulgencio Batista. A new government led by Fidel Castro was later set up. The current Cuban government is considered by the 2010 Democracy Index as "authoritarian".
Cuba is home to over 11 million people and is the most populous island nation in the Caribbean, as well as the largest by area. Its people, culture, and customs draw from diverse sources, such as the aboriginal Taíno and Ciboney peoples, the period of Spanish colonialism, the introduction of African slaves and its proximity to the United States.
Cuba has a 99.8% literacy rate, an infant death rate lower than some developed countries, and an average life expectancy of 77.64. In 2006, Cuba was the only nation in the world which met the WWF's definition of sustainable development; having an ecological footprint of less than 1.8 hectares per capita and a Human Development Index of over 0.8 for 2007.
