Dead Sea

The Dead Sea (Hebrew:‎, "Sea of Salt"; Arabic:‎, al-Baḥr El-Mayyit, "Dead Sea";) is a salt lake between Israel and the West Bank to the west, and Jordan to the east. It is 422 metres (1,385 ft) below sea level,[2] and its shores are the lowest point on the surface of Earth on dry land. The Dead Sea is 378 m (1,240 ft) deep, the deepest hypersaline lake in the world. It is also one of the world's saltiest bodies of water, with 33.7% salinity. Only Lake Assal (Djibouti), Garabogazköl and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond and perhaps Lake Vanda) have a higher salinity. It is 8.6 times as salty as the ocean.[3] This salinity makes for a harsh environment where animals cannot flourish, hence its name. The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. The Dead Sea has attracted visitors from around the Mediterranean basin for thousands of years. Biblically, it was a place of refuge for King David. It was one of the world's first health resorts (for Herod the Great), and it has been the supplier of a wide variety of products, from balms for Egyptian mummification to potash for fertilizers. People also use the salt and the minerals from the Dead Sea to create cosmetics and herbal sachets.

Great Wall of China


The Great Wall of China: (simplified Chinese: ; traditional Chinese: pinyin: Chángchéng; literally "long city/fortress") or (simplified Chinese: ; traditional Chinese: ; pinyin: Wànlǐ Chángchéng; literally "The long wall of 10,000 Li (里)"[1]) is a series of stone and earthen fortifications in northern China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during various successive dynasties. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; it lay farther north than the current wall, which was built during the Ming Dynasty.[2]

The Great Wall stretches over approximately 6,400 km (4,000 miles)[3] from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total;[4] a more recent archaeological survey using advanced technologies points out that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi).[5][6][7] At its peak, the Ming Wall was guarded by more than one million men.[8] It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.[9]
