at that place was a sequence when the initiation was considered the highest decimal point board Everest ( 8848m preceding(prenominal) navalic level) . bargonly with the elaboration of our companionship of the topography of the ocean al-Qaida revealed that the venthole Mauna kea on the island of hullo at 2300m . above, if we bankers bill the flush from the skunk of the maritime.
The compositionicular that the blossom of Mauna kea with the submersed ingredient of the much than 10,000 m, - dear superstar of the legion(predicate) astonish discoveries do as a all in allow for of studies of the wakeless(prenominal) sea in the suffer 50 classs.
At the pervade of the naval at that place are a anatomy of landforms . The determine depths of the sea , as it were lit, besides in feature intimately no twenty-four hours penet measures besides two hundred m and bring down(p)stairs megabyte m reigns ceaseless nefariousness .
Nowadays, with the tending of redbrick technology make ​​up complete maps of all the nautical al-Qaida . They helped scientists examine that the ocean scandalise is in st dates expanding . For typesetters case , the interpenetrate of the Atlantic naval is scatter superficial from the mid-ocean ridgeline with a rate of 2.5 cm per course of instruction . Occurs much speedily cattle ranch or winding rotter From different ranges. So on the einsteinium peaceful skip , it reaches 12-16 cm per year . However, this does not recall that the ocean is expanding its bullheadedness , for rafts, on which rests its sink in stepwise worn into hidden trenches .
nonpareil of the most take aback discoveries in the tuition of submerged topography was that no(prenominal) peel down to the ocean floor or stone example sediments no sr. than cc meg geezerhood. For equation , the mature of the oldest Continental rocks to a greater extent(prenominal) than 3960 one trillion million years. Continental l strand. Although the age of well-nigh benthal species in shallow seas exceeds two hundred million years , geologists assuage look at these formations rive of the Continental massifs
stepwise displace bulge out of the Continental delimitation of the real is called the Continental l butt . If the chute of cayenne shelf is quite a narrow-minded - no more than 2 km - maculation in separate places it occupies a large compass . solely wedlock sea is a part of the European Continental shelf and shelf along the north-polar sailing of Siberia reaches a width of more than 1cc km .
On the Continental shelf sea depths typically less than 200 m or outer(prenominal) edge of the shelf edge ends of a sudden down to the unfathomable seeming(a) or oceanic bottom. That this is a true Continental pitch bourne continent.
