Many found under the shadow of the Earth

Scientists have discovered large mountains in the Earth's banner, which can improve our understanding of how it was created; create a planet.

Most of the schoolchildren learn that the Earth has three seats: a crust, a wheel and a heart, divided into an indoor and outdoor base.

Although that is not wrong, it will leave a number of other strands that scientists have identified within Earth.

In a study published in the Science magazine, data scientists used from a large earthquake in Bolivia to find other mountains and other landscapes of 660km directly wood, which divide its & # 39; high and low torch.

Missing a formal name for a & # 39; This record does not mean that it's "the 660-km boundaries".

For deep-peers into Earth, scientists from Princeton University in the US and the Geodesy Institute and Geophysics in China use the most powerful planetary waves, created by big earthquake.

Earthquake data that is 7.0 or higher, which will shake out on each side that can travel through the other side to its side; planet – and back again.

For this study, the baseline data came from the waves that were built after a large earthquake 8.2 – the largest largest earthquake ever recorded ever – in Bolivia in 1994.

Scientists have used powerful computers to symbolize complex behaviors of scattered waves in the deep Earth.

The technology is dependent on the basic buildings of waves: the ability to bend and turn off; burn.

Just as leaving light waves (reflection) of a mirror or bend (revitalization) when they are through prism, earthquake wavelengths can be reduced; travel simply through unaccompanied rocks but appear or not; wonder when they meet any boundaries or rough ones.

"We know that almost everything is roughly surfaced and so spread," said Princeton's Wenbo Wu at the time of the inspection.

"That's why we see these goals – the distilled places that carry the information about it are rough," said Wu, who is now a post office researcher at Institute of Technology of California in the USA.

"In this study, we investigated dispersed dispersed waves to travel within the Earth to block the Earth's 660-km boundaries," said Wu.

The researchers were surprised by just how rough these boundaries are shorter than the surface level we all face; live.

"In other words, there is a stronger landscape than the Rocky Mountains or the Appalachians at the end of 660-km," said Wu.

This statistical model did not allow precise height, but it is possible that these mountains are more than anything on Earth's surface.

The rough was not as equally scattered, either; just like the shovel is on a seashore and large mountains, boundaries have 660-km boundaries and flat pieces.

The researchers also surveyed a 410-kilometer downstream, at the top of the mid-mantle rod, and they did not get so tough.

"They find that deep lines of the Earth are consistent with what we look at the surface," said the scientist Christine Houser, a professor of the Technology Institute Tokyo not involved in this research.
