It is one of China's Five Great Mountains, and has a long history of religious significance. Originally classified as having three peaks, in modern times the mountain is classified as five main peaks, of which the highest is the South Peak at 2,154.9 metres (7,070 ft)”. – Wikipedia

The Seven Sisters is the 39th tallest waterfall in Norway. The waterfall consists of seven separate streams, and the tallest of the seven has a free fall that measures 250 metres (820 ft). The waterfall is located along the Geirangerfjorden in Stranda Municipality in Møre og Romsdal county, Norway. The waterfall is located just south of the historic Knivsflå farm, across the fjord from the old Skageflå farm. The falls are about 6.5 kilometres (4.0 mi) west of the village of Geiranger. It is part of the Geiranger World Heritage Site.

Lake Assal is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura in the Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some 120 km (75 mi) west of Djibouti city. Lake Assal is a saline lake which lies 155 m (509 ft) below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest land depression on Earth after the Dead Sea and Sea of Galilee.

The Atlantic Ocean Road or the Atlantic Road (Norwegian: Atlanterhavsveien) is a 8.3-kilometer (5.2 mi) long section of County Road 64 that runs through an archipelago in Eide and Averøy in Møre og Romsdal, Norway. It passes by Hustadvika, an unsheltered part of the Norwegian Sea, connecting the island of Averøy with the mainland and Romsdalshalvoya peninsula. It runs between the villages of Karvag on Averoy and Vevang in Eida. It is built on several small islands and skerries, which are connected by several causeways, viaducts and eight bridges – the most prominent being Storseisundet Bridge.

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.

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).
