Tectonic Plates Fit Together
by David Beale June 2014
This is because the continents, now on the surface, were formed half way between the surface and Earth's centre. That is because maximum gravity is towards that area — half way between the surface and the centre.
Gravity happens between all areas with compatible mass. [David Beale believes that gravity is caused by exclusion forces, multi-dimensionally, allowing only compatible materials to accommodate each other in space. Compatible things push each other away less than they are pushed towards each other.] Regardless of the cause of gravity itself, it applies to all objects in space as we know it. Gravity was found to deflect balls towards each other (they were observed in still air by being hung inside towers) which proved the idea that gravity causes the moon to orbit Earth, Earth to orbit the sun...
At the centre of Earth, gravity is equal in all directions except for negligible differences because of Earth's shape and density and the gravity of the moon, the sun...which together only change the position slightly from centre for the spot where gravity is absolutely zero. Gravity from the centre is then towards the half-way area where the most-dense matter collects (allowing for the effects of centrifugal force).
Differences can also be explained for the way the continents fit together now according to the diameter of Earth as it was when they first solidified and aggregated. Firstly, at the time Earth was becoming solid, centrifugal forces would have been stronger, so the most-dense of matter would fall less deeply towards the centre than it could if Earth was not rotating. The most-dense matter would have been centrifuged further from the centre than less-dense matter.
Deep under the surface of continents much matter is less dense than just below the surface. This happened when the layers were formed half-way between the surface and the centre. The layering is evidence that originally the layers used to be closer to the centre where gravity is zero and lighter matter could not displace the heavier matter when both were in in the maximum-gravity band. I'm betting that the inside surface of the oceans have their heaviest materials at the deepest layers closer to the semi-molten layers closer to the interior.
After the highest-melting-point matter solidified and sank to the half-way level, other matter solidified that was more dense. It had a lower melting point than the matter that solidified earliest. Subsequent blast-furnace and chemistry effects led to the original continental-shaped cracked layer being forced by gravity displacement and centrifugal forces (Earth's rotation) until breaking through the oceanic solid thin surface of Earth as it was then.
Whereas lead, gold, iron and other metals and compounds, have lower melting points than many less dense minerals, their oxides and other compounds are lighter than many compounds that form only at lower temperatures. Originally the elements probably formed from homogenous plasma first forming Hydrogen and, as temperatures reduced, then more complex molecules formed. Many compounds and minerals are formed by living organisms, further complicating the difficulties for explaining how so many heavy elements happen to remain on the egg-shell-thin surface of a mostly-molten planet.
During Earth's life, material has been added as objects and dust from space. This matter more than offset Earth's losses of gases.
Inside Earth, under the half-way band, there is nowhere for anything to go, to get out away from Earth. Pressures there would be extremely high. Temperatures, also, are high; tending towards everything becoming hyper-condensed plasma. Matter in Earth's centre has chemical, atomic and physical properties presently only speculated about. Sound's characteristics, in such conditions, are presently a mystery; so sound-wave analyses can produce data that can be speculated about but cannot, yet, describe the true nature of Earth's central areas.
The Earth's crust is moving in sections, constantly. The Earth's internal tides, pulled by the Moon and the Sun, circulate in complex patterns. The main internal tidal pattern type is for solid and semi-solid denser material moving within molten material that is less dense and more homogeneous; and the heavier material centrifuges towards the equator where the surface-speed is the greatest. At the equatorial areas the centrifuged matter changes direction up to more than 90° and heads towards either pole. There, being heaviest and having lost it centrifuged momentum during its long spiral path, it sinks towards the centre. Only a tiny amount of matter can sink from the poles directly to the centre; anything slightly off-centre from the axis gets to be centrifuged, again, towards the surface. Anyway, the falling from the poles, towards the centre, stops at about the half-way band between the centre and the surface, with overshoot depending on the relative density of what is falling from the poles. All the paths of internal movements are cycles and spirals-within-spirals, relative to the average daily rotation, the moon, the sun...and the rotation of the and of the crust.
All the internal tides, in collaboration with cycles of the moon, sun and other planets, combine to form conditionally-stable non-linear systems. The stability points, once crossed, lead to quick changes into alternative stable systems oscillating/moving with different harmonics and patterns. The Earth's magnetic field and the position of the crust, relative to the whole, can change quickly between stable balances.
