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.
Isaac Newton – English physicist and mathematician
Isaac Newton – Died 20.03.1727 (born in 1643), English physicist and mathematician.
Developed the law of universal gravity and other laws of mechanics. He formulated the
principle of conservation of momentum and angular momentum. He created the calculus
of variations. 10. 12. 1684 – His work “De Motu Corporum” about the concept of gravity
and its effect on the orbits of the planets, referring to Kepler’s laws, was read to the
Royal Society by Edmund Halley.
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.
Phenomena on Venus
Phenomena on Venus – The planet Venus, like Earth, has the ozone layer. Rotates inversely to the other planets of the Solar System – from east to west.
Phenomena on Saturn
Phenomena on Saturn – Huge and majestic ring system around Saturn has its own atmosphere. It is the only planet of the Solar System, which has a lower average density than water.
Phenomena on Uranus
Phenomena on Uranus – The axis of the planet lies almost in a plane in which the planet revolves around the Sun. Uranus is the coldest planet of the Solar System (-220 ° C in the atmosphere).
Solar energy – The sunlight is free and inexhaustible
Solar energy – The sunlight is free and inexhaustible. Sun provides three hours on Earth as much energy as they consume the inhabitants of the planet in a year. Solar power plant can be installed on almost any roof or any terrain.
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.
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.
