What is a plate tectonic
Until now it was not clear among scientists how long Tectonic Plates have been moving on the Earth’s crust, now they have got the answer to this question.
What is a plate tectonic : Everyone knows that the Earth’s crust consists of several plates, these plates, which are called tectonic plates, they are on the surface of the mantle inside the earth and also move.
But since when they have been doing this kind of activity, scientists have found new information about it, researchers have found that these plates began to move for 3.2 billion years, whereas scientists thought that it started much later.
What is a plate tectonic
Regarding tectonic plate, it is believed that Earth’s lithosphere is made up of many plates, these plates move on the surface of the earth and many are also on top of each other, due to their collision, earthquake and volcanic eruptions also occur.
Reason for transmission of plates
The combined form of convection wave, cuttack pressure and slab stretch is considered to be responsible for plate movement.
In which convection waves contribute the most.
It is important to note that the convection waves originate from the effect of hot mist, ie magma, due to increase in temperature and decrease in pressure.
- Japan plate
- Philippine Sea Plate
- Caribbean plate
- Iranian Plate
- Arabic plate
Plate tectonic map
In the Pilbara Croton in Western Australia, scientists acquired very old pieces of the Earth’s surface. They found that these pieces were moving at a rate of about 2.5 centimeters per year and their move was about 3.2 billion years old.
Researchers think that this is evidence that these plates moved about 2 to 4 billion years ago, this will give new impetus to research like tectonic activity, these plates are called tectonic plates.
Why is this evidence considered important
Researcher alec brenner of harvard university said, “Based on the evidence we have found, the process of plate tectonic may have started much earlier”, the researchers went to pilbara craton in western australia to study.
The Cretan is a very thick, but stable rocky part of the shape of a paramid, it can also be called part of the surface of the earth, it is the center of the tectonic plate and they are like the heart of the ancient continents of the earth, so the information about them would be very solid, it was decided.
Researchers took samples in 2017 and studied them with mognometers and other equipment at the Cambridge Lab, this revealed to them the magnetic history of the rock.
This showed that they would have been built 3.2 billion years ago, when the team compared its data to the data of other researchers doing research on the surrounding rocks, it found that these rocks were slipping 2.5 centimeters every year.
