3 of the most interesting science trailers through February 2019



The land will hide several mountain ranges in the & # 39; his coat. Planet Biru has three basic rows, which is 7.7 billion people living in a crust and about 9 million other species; it's a strong rock in her; banner and 84 per cent of Earth's measure, and volcanic stimulation and earthquake; and the heart that reinforces massive areas around the world.

But between these lines, it appears that anatomy is more specific. The area that translates to the region is called the transition range. line to the upper and lower lines, with the deepest part of a 660km boundary area.

Now, geologists have discovered that these borders hide many mountains, according to researchers who report their results in a new study published on 14 February in the magazine ScienceSouth Westerly

This mountain range is more complicated, with a huge difference in height, rather than mountains commonly seen on the surface, such as the Rocky Mountains and the Appalachian mountains in North America, which is said by the University of Princeton.

So, scientists can find this mountain range, buried at about 410 miles below the Earth's surface, the ground must first be "shaken".

In collaboration between Princeton University and the Geodesy Institute and Geophysics in China, experts analyzed data from a 8.2 earthquake that was raped in Bolivia in 1994.

The strong slab may be able to put waste tonnes inside the Earth, sometimes through the heart, move to the other side and back again. Psychologists can monitor the intensity of those excavated waves at different points on the surface of their planet, when a logo is pulled up; left on either side. Seasons vary according to their knowledge.

Seismologists can find out how many tonnes are scattered on the surface and use the data available to find out what is under the Earth's surface.

In the new study, researchers created symbols like the top of the movement zone and its base (660 km boundary) in the Earth banner.

Although they found rough at the end, they did not; They can explain whether the mountains are higher than those on Earth's surface.

As with what is found on the surface, the area's landscape is slightly different. In addition, at the very top of this zone, about 410 kilometers down (255 miles), found a bit rough.

With these conclusions, scientists can understand how the planet is created and how it works now. However, an explanation has yet to be made if the upper and lower puppies are tied up or stand alone with their own chemical compound.

Over the years, geologists continue to debate this range of transition and are said to keep the upper and lower eyes from their; come together. But the newly discovered landscapes are able to show out if they are mixed or not.

Areas can be caused by their boundaries by clicking on the # 39; The combination of two strands, and more acute areas can arise because they can not mix well in these places, and create inventories, researchers said.

The sediment itself can come from rocks that move long from the mast to its; messenger, now near the 660 km limit, it may be just below or just over.

"It's easy to get in, because we can only find loose waves that travel across the Earth in current situations, that sectors can not support how the side Interior of the Earth has changed over the past 4.5 billion years, "said co-author of the study Jessica Irving, geologist at Princeton University.

"It is interesting about this product that this Earth's activity gives us new information to understand the origin of old tectonic pests that have come down to the banner, and where old banner material can still be present."
