Antarctica, The Ice Continent

L'Antartide è un continente grande due volte l’Australia, ricoperto quasi interamente di ghiaccio, con deserti polari, montagne, vulcani e laghi subglaciali. In questo video ti raccontiamo questa terra misteriosa e affascinante abitata da una grande varietà di animali polari.

Antarctica is Earth's southernmost continent. It is a pristine, inhospitable landmass, twice the size of Australia, and almost completely covered in ice. The name Antarctica is derived from a Greek word meaning "opposite to the north.”

Antarctica has six-month dark winters when temperatures can sink to nearly -90C, with winds of over 300 km/h. It has no native human population. Certain animals, however, thrive there, including whales and seals, seven species of penguin and a number of other bird species.

Sightings of the continent were first recorded in 1819, by a Russian and then a British ship.
Famous explorers of the continent include Briton Ernest Shackleton, who crossed its Transantarctic Mountains in 1909, the Norwegian explorer Roald Amundsen, who discovered the South Pole in 1911, and the Danish-Norwegian explorer Caroline Mikkelsen, who in 1935 became the first woman to set foot on Antarctica.

Since 1959, the continent has been governed by an international treaty that established it as a scientific reserve and banned military activity. Today, a number of permanent research stations exist there to study and protect its unique ecosystem.

Natural phenomena in Antarctica include the aurora australis or ‘southern lights’: a glow in the night sky created by solar winds that pass by the Earth. Another spectacle is ‘diamond dust’, a ground-level cloud composed of tiny ice crystals.
