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.

by Edmund Halley.

Pluto position loss

Pluto position loss - Pluto

Pluto position loss

Pluto position loss – At the General Assembly of the International Astronomical Union in Prague in 2006. It was decided that Pluto is not a planet. On the ballot passed the definition of a planet. Pursuant to the findings of a celestial body being a contender for this name must circulate orbit. Its mass and gravity to be so large that formed the shape of a round. In addition, there should be other large bodies in their neighborhood.

Earth’s magnetic field weakening

Earth's magnetic field weakening - North magnetic pole

Earth’s magnetic field weakening

Earth’s magnetic field weakening – Swarm mission, launched by the European Space Agency (ESA), launched in 11.2013. Satellites of this mission performed photos, which showed that the magnetic field of our planet is still weakening. The measurements confirmed the movement of the Earth’s North Pole to Siberia. Scientists will now investigate whether this is a temporary trend, or constant.

International Space Station ISS

International Space Station ISS – The date of the creation of the ISS is considered 20 November 1998. Then the orbit brought out the first element. It was the Russian module Zarya. ISS has been inhabited since 2 November 2000. It is located on a low earth orbit. Circling the Earth at an average altitude of 400 km. The height is adjusted, but the ISS is still lowers its flight. While planning the trajectory taken into account the availability of spaceports in Russia and the USA. One lap around the earth station takes approx. 92 minutes, so a day circling the planet 15.7 times. Compared to the Earth’s surface moves at a speed of 7700 m / s, or 27720 km / h.

Triton – similar to construction of Pluto

Triton - Neptune's moon

Triton – similar to construction of Pluto

Triton – In the realm of Neptune there is unbelievable frost. The temperature drops below -200 °C. Similar chill prevails on the moons of the planet, the largest of which is this moon. On the surface temperature of approx. -235 °C. However, the processes within the satellite dissolve the ice, so that under surface of the ocean exists. The composition of this satellite, is similar to the construction of Pluto. In contrast to the other large moons of the planets in the Solar System, it moves retrograde. Which indicates that it probably was once a dwarf planet in the Kuiper Belt.
