Where is the world’s Saltiest sea? The Dead Sea is in south-west Asia and is a really big lake . Its northern half belongs to Jordan and its southern half is divided between Jordan and Israel. It covers an area of 394 square miles and contains about 11,600,000,000 tons of salt. The River Jordan , which contains only 35 parts of salt to 100,000 parts of water, flows into the Dead Sea and each year adds 850,000 tons of salt to the total. The lake’s surface level lies 1,302 feet below the Mediterranean and is the lowest sheet of water on earth. In summer the absence of rain and the high rate of evaporation cause the water level to drop between 10 and 15 feet below that in winter. There is no outlet from the Dead Sea, but water balance is maintained by evaporation.. Blue-white clouds, which form a mist over the surface of the water, carry of the vaporated moisture. The Dead Sea is mentioned many times in the Bible. It gave its name to the Dead Sea Scrolls, groups of leathe...

OCEAN CABLE The laying of the first successful transoceanic cable was completed on July 27,1866, from Newfoundland, Canada to Valencia Island off the south-west coast of Ireland. The cable was laid by the famous steamship Great Eastern. Since that time submarine telegraph and telephone cables have been laid all over the world. Today the longest submarine telephone cable is the Commonwealth Pacific Cable (COMPAC). It runs for over 9,000 miles from Australia, via Auckland, New Zealand and the Hawaiian Islands to Port Berni in western Canada. This cable was officially inaugurated on December 2,1963. Its total cost was about  £35 million. Now the communications by the satellite are being extensively used, it seems unlikely that another cable will ever be built to match COMPAC's record.

What is the world's heaviest metal?      The heaviest metal in the world is iridium. It was discovered in 1804 by Smithson Tennant of the United Kingdom. Iridium, which is a silvery-white of the platinum group, weighs 1,414 pounds a cubic foot or roughly two-thirds of a ton. Lithium, the lightest metal, weighs 33 pounds per cubic foot.      If you could stand an elephant weighing nearly six tons at one end of a seesaw, you would need only a two-foot cube of iridium at the other end to lift the animal. Such a cube would cost nearly £15,000,000.

Where is the hottest place on earth?      For sheer consistency the hottest place in the world is Lugh Ganane in Somalia, east Africa, where the temperature never falls below about 31°C (88°Fahrenheit).      However, the hottest temperature ever recorded was in 1933 at San Luis Potosi in Mexico where about 58° Centigrade (120° Fahrenheit) in the shade was recorded.      In California in 1917 temperature about 49° C (120° F) were recorded on 43 consecutive days -- in Death Valley, not surprisingly.      Western Australia also has more than its fair share of sunshine. At Marble Bar, for instance, the temperature remained around 100° F for 160 days and in 1946 at Wyndham, again in Western Australia, the temperature reached 90° F or more, for almost the whole year (333 days to be exact).

Where is the highest railway in the world?      The highest railway in the world is in Peru. A branch siding of the track rises to 15,844 feet above sea-level. But the highest point on the main line is 15,688 feet in a tunnel called La Galera.      All the railway lines in Peru belonging to the Central Railway of Peru are of standard gauge (4 feet 8 ½  inches), like most railways in Europe and North America.      The highest railway station in the world is also in Peru, at La Galera. This station is at an altitude of 15,685 feet above sea-level. Henry Deiggs was the engineer for this extraordinary railway line, which was completed nearly a hundred years ago.

What causes the tide to change? The highest tide in the world is recorded in the Bay of Funday which is between New Brunswick and Nova Scotia in Eastern Canada. There the Petitcodiac River narrows, and forces the inrushing tide to the greatest height found anywhere on earth. The difference between high water and low water in the Bay of Fundy is no less than 50 feet. Fishermen make use of these extreme tides as you see in the illustration. They set their nets at high tide and collect their catch of fish when the tide goes down. Tides throughout the world are caused by the varying power of the pull of the sun and the moon on the oceans. They draw the water up in a great wave, and the rotation or spin of the earth every 24 hours sends this wave round the world washing the coasts of the continents and islands. The varying shapes of the coastlines and inlets also affect the tides, and, therefore, ports and navigation. At certain times of the month, the sun and moon are said to be ...

The bridge with the longest span is the Verrazano-Narrows Bridge, which stretches across the entrance to New York City from Staten Island to Brooklyn. Work on the project began on August 13, 1959. The bridge was opened to traffic on November 21, 1964. It measures 6,690 feet between supports and carries two decks, each of six lanes of traffic. The centre span over water, is 4,260 feet, the world record. The bridge carries well over 20 million vehicles a year.
