Even inside the earth there is a huge "ocean".

<P> Scientists scanning the deep interior of Earth have found the following in East Asia there is a huge reservoir of water which is equivalent to an Arctic Ocean water. .The figure on the left is a section diagram on the right figure, showing 620 miles of underground attenuation of seismic waves at the mantle anomaly. .Two pictures in abnormal red rock soft and fragile, is that which is high in water, blue exception of hard rock (the middle value between white and yellow). .</ P> <P> man first discovered in the deep mantle under the giant body of water </ P> <P> According to LiveScience, scientists scan in the deep interior of the Earth found that there is in East Asia following a very large .Reservoir, which is equivalent to a moisture content of the Arctic Ocean water. .</ P> <P> This is the man first discovered in the deep mantle below such a large body of water. .</ P> <P> The discovery by a seismologist at Washington State University and his student Michael Wysession University of California, Jesse Lawrence of drawn together, it will be published in the American Geophysical Society published a special issue. .</ P> <P> both of them with nearly 60 million copies of the seismic map (seismic waves through the Earth's records produced by the devices distributed around the world collected.) .</ P> <P> They note that the following seismic waves in the Asian continent, has shown less common, but slightly slower speed, Wysession said: "The water can slow down the speed of seismic waves, a large number of weaker and slower .where signs can predict the existence of water. "</ P> <P> previous forecast calculated that when the submarine sank to the icy rock of the mantle were thousands of miles underground, the underground temperature deep in the water will evaporate out of the rock which .. .</ P> <P> Wysession said: "That is what we want to show here, the rock strata which together with the water as the submarine sank, and it is very cold, but the increase with depth, the temperature began to rise ., the rock became unstable, lost water contained. "Then the water began to rise into the overlay area, where the saturated zone into the water," but there still looks like a solid rock, but you have to put it .to the laboratory to find one of the water. "</ P> <P> Although they look like solid rock, some 15% of submarine rocks are water. .Wysession explained: "In fact the water molecules present in the mineral structure of rock. When you put it, when heated, it will be dehydrated, as a piece of clay by fire, as you can to remove all the water inside." .</ P> <P> researchers estimate that the Earth's surface in those areas covered by water, as long as 0.1% of the rock sinking into the mantle can produce the equivalent of an Arctic Ocean water. .</ P> <P> Beijing exception </ P> <P> Wysession structure of this new underground known as the "Beijing anomaly," because it found in the Chinese capital Beijing, following the decline of the value that the largest seismic wave. .Wysession first used the term in a commentary in the Beijing University. .</ P> <P> Wysession said: "They feel very very interesting, the threat of earthquake in China than in other parts of the world are large, so they are very interested in seismology." </ P> <P> the Earth's surface .70% covered by water, the water has a lot of role, one of which is the movement of continental plates act as a "lubricant" role. .</ P> <P> "Look at our sister star, Venus," Wysession said, "in its internal very hot very dry, it does not have plate tectonics, all the water may have evaporated, and also .No plate, its whole system is blocked, just like the Wizard of Oz in that no oil and, like tin rusty.
