The strange and weirdly beautiful terraced pools of Pamukkale have been appreciated for over two millennia and yet still remain a little known wonder of the world. Thousands of years ago earthquakes, which are common in Turkey, created fractures that allowed powerful hot springs to bring water rich in calcium carbonate to the surface.
Pamukkale, meaning “cotton castle” in Turkish, is a natural site in Denizli Province in southwestern Turkey. The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water. It is located in Turkey’s Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.
Moeraki is a small fishing village on the east coast of the South Island of New Zealand. It was once the location of a whaling station. In the 1870s, local interests believed it could become the main port for the north Otago area and a railway line, the Moeraki Branch, was built to the settlement and opened in 1877. However, the port could not compete with Oamaru and the lack of traffic as well as stability problems caused by difficult terrain led to the closure of the railway in 1879 after only two years of operation.
3. Nine Hells of Beppu
Beppu, located on the Japanese island of Kyūshū, is the second largest producer of geothermal water in the world. Located in the same area are the “Nine Hells” or ponds that each has its own remarkable character and colour thanks to the variety of minerals in the outflows.
4.Las Cañadas – Tenerife
Mount Teide is a volcano on Tenerife in the Canary Islands. Its 3,718-metre summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic. At 7,500 m (24,600 ft) from its base on the ocean floor, it is the third highest volcano in the world, after Mauna Kea and Mauna Loa in Hawaii. Its altitude makes Tenerife the tenth highest island in the world. It remains active: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift.
5.Great Blue Hole
The Great Blue Hole is a large submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km from the mainland and Belize City. The hole is circular in shape, over 300 m across and 124 m deep. It was formed during several episodes of quaternary glaciation when sea levels were much lower. Analysis of stalactites found in Great Blue Hole shows that formation took place 153,000, 66,000, 60,000, and 15,000 years ago.
