What are some of the most polluted bodies of water in the world?

What two canals join the world's seas? What bodies of water do they connect?

• Answer:

  SUEZ CANAL: It is an artificial waterway running north to south across the Isthmus of Suez in northeastern Egypt; it connects the Mediterranean Sea with the Gulf of Suez, an arm of the Red Sea. The canal provides a shortcut for ships operating between both European and American ports and ports located in southern Asia, eastern Africa, and Oceania. The Suez Canal is 163 km (101 mi) long. The minimum bottom width of the channel is 60 m (197 ft) and ships of 16 m (53 ft) draft can make the transit. The canal can accommodate ships as large as 150,000 dead weight tons fully loaded. It has no locks, because the Mediterranean Sea and the Gulf of Suez have roughly the same water level. The canal utilizes three bodies of water—Lake Manzilah, Lake Timsāh, and the Bitter Lakes (the latter is actually one continuous body of water)—and is not the shortest distance across the isthmus. Most of the canal is limited to a single lane of traffic, but several passing bays exist, and two-lane bypasses are located in the Bitter Lakes and between Al Qanţarah and Ismailia. A railroad on the west bank runs parallel to the canal for its entire distance. PANAMA CANAL: It is a canal across the Isthmus of Panama, in Central America, that allows vessels to travel between the Pacific and Atlantic oceans. The waterway measures 64 km (40 mi), including dredged approach channels at each end. The Panama Canal handles a large volume of world shipping and enables vessels to avoid traveling around South America, reducing their voyages by thousands of miles and many days. The canal consists of artificially created lakes, channels, and a series of locks, or water-filled chambers, that raise and lower ships through the mountainous terrain of central Panama. Built by the United States from 1904 to 1914, the Panama Canal posed major engineering challenges, such as damming a major river and digging a channel through a mountain ridge. It was the largest and most complex project of this kind ever undertaken at that time, employing tens of thousands of workers and costing $350 million. KKG
