Our World Heritage: The land continues to rise by about 9 mm per year and still affects the landscape. Even today, new flads are being formed and new De Geer moraines and cobble fields are emerging from the sea thanks to land uplift.
Other World Heritages: Some World Heritage Sites are quite young. The Surtsey World Heritage Site, a volcanic island south of Iceland, was formed by a volcanic eruption that lasted almost four years. On 14 November 1963, the volcanic island rose above sea level. The Sydney Opera House is also a young World Heritage Site, opened in 1973
