Tectonic plates – Moving very slowly

Tectonic plates – The Earth looks fixed, but the development of our planet is still not completed,
and the earth is still working. The main reason is the movement of tectonic plates.
Plates
are moving very slowly, a few centimeters per year. If will move up rapidly,
there is
an earthquake. In the history of geological face of the Earth has changed several times.
With
Pangea formed several continents we know today. The plates can move in several directions.
They can
glide along each other, and then the friction releases huge amounts of energy in the
form of
earthquakes. When the plates glide against each other, then either one plate thrusts
under the second
or push against each other, causing uplift – this is how the Himalayas,
the highest mountains
in the world. The plates can also move away from each other,
such
as plates in the African Great Rift Valley.

Moonless development – Earth without Moon

Moonless development – Earth without Moon

Moonless development – Earth without Moon – Simulations 4 billion years of
development of the Earth without the presence of the Moon. Were performed in the
Research Center of NASA in Moffett Field, California by Jack Lisauer.
In the developed model,
the maximum angle at which leaned to the axis of the Earth, turned out to be much smaller
than
assumed earlier studies. The conclusions of the study were: Earth would be the Earth,
even without
his extremely large satellite.

Molecules from space – Primary gas after Big Bang

Molecules from space - Universe expansion

Molecules from space – Primary gas created shortly after Big Bang

Molecules from space – Primary gas created shortly after Big Bang – Has been confirmed the
hypothesis
about the origin of molecules from space. The researchers were able to discover
the so-called
. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen
and
its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the
lightest
chemical elements, hydrogen and helium. Heavier elements appeared only after 100 Mln years.

Brussels tunnel – Experiment with photocatalysis

Brussels tunnel – Experiment with photocatalysis

Brussels tunnel – Experiment with photocatalysis – In 09.2011. European experts began their
experiment
in the Brussels tunnel, through which passes every day 25 thousand. cars.
100
meter length of building was covered with cement with titanium dioxide TiO2,
which
is the source of a chemical process called photocatalysis, acts as a catalyst driven by
solar radiation
(UV).

Seikan railway tunnel – Honshu and Hokkaido connection

Seikan railway tunnel – Honshu and Hokkaido connection – In 13. 03. 1988 was opened Seikan
rail
tunnel linking the Japanese islands of Honshu and Hokkaido.
The length of the tunnel is 53.84 km
(more than 23 km is under the sea floor). It is the world’s longest undersea railway tunnel.
