The movement of continents again became inexplicably

March 28. A team of scientists funded by NASA found that the asthenosphere of the Earth is not the main reason for the movement of continents. Science once again have to revise many of the details of plate tectonics, which are changing the face of our planet.

Asthenosphere — a layer of partially molten rock at a depth of 35-120 km. The outer layer of the Earth (lithosphere) is divided into many tectonic plates. Under the ocean lithosphere is relatively thin (about 100 km), and thicker under the continents (320 km). Beneath the lithosphere is the asthenosphere, plastic and partly

The theory of plate tectonics — in doubt

April 19, 2013. If you look at the geological map of Alaska, you can see the regions where the layers of rock in a strange way "fused" with the platform. South Alaska — a cluster of fragments of all shapes and sizes, each of which is ready to tell his story. All of them — "exotic terranes", formed in different places? At different times. What forces carried them here, and why some of them are deployed relative to its neighbors — is a mystery.

Some exotic terranes — a native of the regions on the other side of the

At the South Pole in the icy mountain found fragments of dinosaur skeletons, dating back about 200 million years. Fossils supposedly belong early ancestor Brontosaurus representative of fossil animals, widely known thanks to his long neck and massive body.

Already recovered about 900 kg of fossils from

Earth expects great redistribution of continents

Forecast

3.03.11.Uchenye say that in the future appearance of the planet can change before neuznavaemosti.Ocherednym confirmation that the appearance of the continents, even as their number, change of discoveries in South America. It found two quite mysterious cracks that appeared "under mysterious circumstances". Fault or failure in the ground three kilometers long and 100 meters wide was found in Peru, near Lake Titicaca. Other — much longer — in Bolivia. Scientists have no explanation for their occurrence. We have previously reported on the formation of the fault in Africa, which threatens to divide the continent into two almost equal parts.

One for all the mega-continent

April 24, 2012 9:26

You never were concerned about how it will look from space Earth in a few hundred million years?

Geologists believe that billions of years ago the continents disconnected again "eager" to meet, to unite and form a common, but a vast continent, Pangea Supernova.

This continent is, of course, will be polar, which is not particularly good for our very distant descendants, but how do we know who will be at that time living in our beloved planet.

If you believe the conclusions of scientists, similar supercontinent existed on the planet and a very, very

Scientists: the Earth has a pulse

Scientists from the University of Kansas, USA, believe that the Earth is a kind of pulse — about once every 60 million years of the continents rise, only to fall back on.

What kind of tectonic mechanism causes the Earth to pulse, while not entirely clear, but is likely to be explained by these rises mysterious mass extinction of marine life, has been at least 500 million years, occur if the schedule to this periodicity. During the rise of the continents of the sea are too small length of many species, which does not allow them to survive.

Scientists have discovered a link between magnetic reversal and tectonic plate movement

    October 30. Earth's magnetic field is generated by the movement of liquid iron in the core at a depth of 3 kilometers. What led researchers to think about the relationship between tectonic plates and the magnetic field? The discovery that the convective flow of liquid iron play a role in the creation of the magnetic poles: experiments and modeling conducted over the past five years have shown that recovery occurs when the movement of the molten metal are no longer symmetric with respect to the equatorial plane. This "symmetry breaking" may be gradual, starting with the area at the

In the recent, in geological terms, the future, all the continents and islands of the Earth can merge. The recent earthquake in Southeast Asia proves that the continents gradually approach each other, and after 250 million years, all the continents of the Earth "unite" in a single
