A BRIEF EARTH HISTORY AND THEORY OF PLATE TECTONICS
One major segment of current geological is consentrate to life form at the geological boundaries. A brief overview of one model explaining these event is given below.
For the first we can talk about a clue from meteorit. The meteorites are the left-overs from the creation of the solar system, that up to 19% water locked up in their mineral structure. Upon heating, this water is given up, and the mineral turns to olivine. The earth’s mantle is large composed of olivenes.
The second, The role of radioactive decay. After the creation, the interior of the earth heat up to the rapid decay of short radioactive elements as a result of hight speed values, and this radioactive heating drove the water out of a lot or minerals in the mantle the earth’s surface. The radioactive heating continue and continue, more and more and that’s make a forming the tectonic plates. This pressure was increased by the expansion of mantle rock through heating.
The flood layer in geology, this event dates from the infra-cambrian around 600 million years ago atomically, and this converts to 3536 BC when the atomic clock is corrected for variation. This quartzite resulted since the water in the earth” interior was rich in silica.
In the second catastrophe, the radioactive heating of the erath’s interior continued made the mantle become molten and that’s episode of rampant volcanism followed.
The change in atmosphere brought about by volcanism produced a dry and windy elimate generally. The land full with the big reptile, big amphibi, old plan, and that’s has found in the next million years, and called fossil.
The continent divide, the major impact of the series of the Yucatan (near the mid-Atlantic rift) accelerated the rate of continental drift. The impact appears to have increased the axis tilt to something of the order of 28 degrees or more. When the temperature back to the present 23,5 degrees, that’s make the land hidden deeply on ice, and we called tha t the ice age.
Plate tectonic theory, that’s the theory that earth’s outer layer is made up of plates, which have moved throughtout earth”s history. The theory explained how and why behind mountains, colcanoes, and earthquake, and this theory explained similar animals culd have lived at the same time. Exactly what drives plate tectonics is not known. One theory is that convection within the earth’s mantle pushes the plates, and in the same way that air heated by your body rises upward and is deflected sideways when it reaches the ceiling.
And the other theory, is a gravity, the gravity is pulling the older, colder, and the heavier ocean floor with more force then the newer, lighter, and seafloor.
Plate tectonic activity takes place at four of boundaries, first, divergent boundaries is, where new crust is formed, the second is convergent boundaries, that means where crust is consumed, the thirdh is collisional boundaries, that’s mean where two land masses collide, and the last is transform boundaries, that is mean, where two plate slide against each other.
