The Future of Our Earth
And the thinnest layer is the bark.
According to scientists, the inner core of the Earth is in a solid state as a result of strong pressure, unlike the outer core, which is represented in a liquid state.
It is believed that the inner core consists mainly of nickel and iron.
The average radius of the Earth is 6371 km.
Another interesting feature is plate tectonics. Continents, oceans are our planet. But continents, as if alive, move.
It is also hard to believe that a supercontinent once existed.
The German scientist Alfred Wegener (1880-1930) called such a supercontinent that emerged in the Paleozoic era Pangea.
He noticed that the coasts of South America and Africa, separated by the Atlantic Ocean, have an amazing similarity. The scientist also drew attention to the flora and fauna of both continents.
Based on these and other scientific data, Alfred Wegener proposed the theory of slow continental drift. The essence of this theory is that due to the movement of the Earth's mantle, the continents are drifting.
But why are the continental plates moving? What forces are capable of moving such gigantic segments of the Earth?
Alfred Wegener explained this by the movement of centrifugal forces, as well as the action of the Sun and Moon.
Robert Sinclair Dietz (1914-1995) and Harry Hammond Hess (1906-1969) proposed a hypothesis that currently holds a leading place. Plate tectonics, according to this version, is associated with convection currents in the mantle, which leads to the movement of continents.
There were other hypotheses. But it will probably be interesting to know another version of continental drift.
The existence of a supercontinent, when the entire land was united into a single whole, is no longer in doubt. This is accepted as a fact.
Perhaps all the continents were also a single whole during the formation of the planet.
That is, if we collect all the continents, we will get an ancient planet. Therefore it will become clear that the Earth earlier was smaller sizes.
Then it will be interesting to know what the original dimensions of the planet were?
These dimensions can even be calculated by simple mathematical actions.
It is known that the total land area of the planet is149 939 063,133 km².
We also know that the equatorial radius of the Earth is 6378,1 km. The average radius is 6371,0 km.
Now let's move on to the calculations.
The area of the ball: S = 4π∙R².
The land area of the Earth is 149 939 063,133 км².
R = √S/4π
R= √149 939 063,133/4∙3,14 = √149 939 063,133/12,56 = √11 937 823,4979 ≈ 3455,115 ≈ 3455 км.
It turns out that the radius of the primary Earth was 3455 km.
Based on these results, the radius of the Earth was 3,455 km, and in order to reach its current size, the planet expanded.
Thus, at the dawn of the birth of the Earth, the entire planet was covered with water. Increasing in size, the Earth's crust was torn apart, forming continents. The resulting spaces were filling with water. Solidified magma formed the bottom of the oceans.
Further expansion of the Earth led to subsequent ruptures and the emergence of already other land areas.
If the radius of the ancient Earth was 3455 km, then the planet rotated around its axis faster than at present.
A day is a unit of time corresponding to the period of rotation of the Earth around its axis. Currently, a day is 24 hours long. But it was not always so.
Scientists, based on many studies, have found out that the speed of rotation of the Earth around its axis is decreasing. So in 1962, it was found that 350 million years ago, the year was 385 days, that is, the duration of the day was less than 23 hours. These data were obtained on the basis of a study of fossil corals.
We continue our reasoning.
During volcanic eruptions, hot lava flows out. And this suggests that there are high temperatures inside the Earth, which means our Earth is alive, it has energy. This energy, the energy of the Earth, has given and is giving life to our planet.
