It depends where you measure. On average, it is about 4000 meters. The deepest place is the Marianas trench, which is more than 11,000 meters deep. \n\nHere is a table from the reference:\n\nOcean Average Depth (feet)Average Depth (meters)\nPacific 13,740           4,188\nAtlantic 12,254           3,872\nIndian 12,740           3,872\nArctic 3,407            1,038\nAverage Overall 13,124     4,000\n\n\nOcean Deepest  Point Depth (feet) Depth (meters)\nPacific Mariana  Trench 36,200      11,033\nAtlantic Puerto  Rico Trench  28,374     8,648\nIndian Java Trench        25,344     7,725\nArctic Eurasia basin 17,881     5,450

The Mariana Trench (or Marianas Trench) is the deepest known submarine trench, and the deepest location in the Earth's crust itself. It is located in the floor of the western North Pacific Ocean, to the east of the Mariana Islands at 11°21′N 142°12′E, near Guam.\n\n[edit]\nDescription\nThe trench is the boundary where two tectonic plates meet, a subduction zone where the Pacific Plate is being subducted under the Philippine Plate. The bottom of the trench (Challenger Deep) is farther below sea level than Mount Everest is above it. The trench has a maximum depth of 10,911 meters (35,798 ft) below sea level. Taking into account its latitude and the Earth's equatorial bulge, this puts it at 6,366.4 kilometers (3955.9 mi) from the centre of the Earth. The Arctic Ocean, on the other hand, is about 4,500 meters (14,800 ft) deep, which would put its floor at 6,353 kilometers (3947 mi) from the Earth's center, some 13 kilometers (8.5 mi) closer.\n\n[edit]\nExploration\nThe trench was first surveyed in 1951 by the Royal Navy vessel Challenger II, which gave its name to the deepest part of the trench, the Challenger Deep. Using echo sounding, the Challenger II measured a depth of 5,960 fathoms (10,900 m, 35,760 ft) at 11°19′N 142°15′E. This sounding was repeatedly made using earphones to hear the return of the signal as the stylus passed across the graduated depth scale, whilst the timing of the speed of the echo-sounding machine, a necessary part of the process, was made with a handheld stopwatch. For these reasons it was considered prudent to subtract one scale division (of 20 fathoms) when officially reporting a new greatest depth of 5,940 fathoms (10,863 m).\n\nIn 1957, the Russian vessel Vityaz reported a depth of 11,034 meters (36,201 ft), dubbed the Mariana Hollow; this measurement has never been replicated and is not considered accurate. In 1962, the M.V. Spencer F. Baird recorded a greatest depth of 10,915 meters (35,810 ft). In 1984, the Japanese sent the Takuyo, a highly specialized survey vessel out to the Mariana Trench and collected data using a narrow, multi-beam echo sounder; they reported a maximum depth of 11,040.4 meters1 (this is also reported as 10,920±10 meters).2 The most accurate measurement on record was taken by another Japanese probe, Kaiko, on March 24, 1995: 10,911 meters (35,798 ft) 3.\n\n \nJanuary 23, 1960: Trieste just before the diveIn an unprecedented dive, the United States Navy bathyscaphe Trieste reached the bottom at 1:06 p.m. on January 23, 1960, with U.S. Navy Leuitenant Don Walsh and Jacques Piccard on board. Iron shot was used for ballast, with gasoline for buoyancy. The onboard systems indicated a depth of 11,521 meters (37,800 ft), but this was later revised to 10,916 meters (35,813 ft). At the bottom, Walsh and Piccard were surprised to discover soles or flounder about 30 cm (1 ft) long, as well as shrimp. According to Piccard, "The bottom appeared light and clear, a waste of firm diatomaceous ooze".\n\nAt the bottom of the Mariana Trench, water exerts a pressure of 1,086 bar (108.6 MPa or 15,751 psi), over 1,000 times the standard atmospheric pressure at sea level.\n\nIn the fictional movie The Core, the Mariana Trench is chosen as the entry point for the Journey to the center of the earth.

Do you mean the Marianas Trench, the deepest trench in the world? It is close to the Philippine Islands, but closer to the Marianas islands.

The world's deepest lake is Lake Baikal, in Siberia, Russia. The deepest point of the lake, the Olkhon Crevice, has a depth of 1,637 m (5,371 ft), of which 1,181 m (3,875 ft) are below sea level. It is also the oldest freshwater lake on Earth, having formed between 20 and 25 million years ago. Baikal also contains one-fifth of all the world’s fresh surface water! The lake is roughly crescent-shaped, 636 km (395  miles) long, with a surface area of 31,500 km² (12,200 miles²).

There are 2 people who should be considered. The first one is a herdsman from the Inner Mongolia region of China, Bao Xishunto a.k.a. Xi Shun (b. 1951), measured 7' 8.95" (2 m 36.1 cm). He has been confirmed by Guinness World Records as the tallest naturally-growing human in the world in January 2005. \n\nBut that's not all, there is a Ukrainian veterinary surgeon, Leonid Stadnik, and he is believed to be 8' 4" inches tall and thought to be still growing! He considers his condition "God's punishment" and doesn't want to be considered for the world record title, hence he has refused so far to be measured by officials of the Guinness Book of Records.\n\nBy the way, the tallest man ever recorded was an American by the name of Robert "Pershing" Wadlow (1918-1940), born and buried in Alton, Illinois. His height of 8' 11.1" qualifies him as the tallest person in history, as recorded in the Guinness Book of Records.

The Red Sea is not the lowest point on earth.  However, I do believe that you are thinking of the Dead Sea!  The Dead Sea is one of the lowest points on earth, and water that flows into it does not flow back out (it is called the dead see because it is so salty that no living thing can survive in it.  It's so salty that it actually makes it easier to float!)  The actual lowest point on earth is Mariana's trench, which is in the pacific ocean near Southeast Asia.  I believe that the depth is around 28000 feet (the last time I knew, no submarine had ever touched the bottom, but they did come to within about 3 feet of the bottom).  I hope that that sufficiently answered your question.

"Scientists using NASA's Rossi X-ray Timing Explorer have estimated the depth of the crust on a neutron star, the densest object known in the universe. The crust, they say, is close to a mile deep and so tightly packed that a teaspoon of this material would weigh about 10 million tons on Earth."\n\nhttp://spaceflightnow.com/news/n0604/24starquake/
