As the Earth span and cooled, the heavier material was drawn to the centre to form the Earths core, and the lighter material was forced out to the surface, thus forming various layers of dense material.
The closer you get to the Earths core, the denser and hotter those layers of material get. In fact the gravitational pressure at the Earths core is so great, that if you were to suddenly find yourself their, the pressure of gravity would crush your body to the size of garden pea.
Above the earths core we have the mantle and asthenosphere which is where flowing lava comes from. This is comprised mostly of silicon-magnesium (named SIMA), and on top of this layer floats the crust, which is the outer layer of our planet that we live and build our houses on.
The crust, for obvious reasons, is the most widely studied and understood layer of our planet. It is made up almost entirely of silicon and aluminium atoms which are bonded with oxygen hence the name SIAL.
Above the SIAL we have the ocean or Hydrosphere, which takes up two thirds of the planets surface, and above that we have the various gasses that make up the air we breath or Atmosphere.
This diagram shows a cross section of the earth, to illustrate the various layers of our planet.
Our planet is not unique in its layered formation, and according to NASA, virtually all large planets and moons form layers this exact same way. But there is one thing that does make the Earth unique…
Almost three fourths of the Earths outer layer (the rocky SIAL or crust) is missing, it quite simply doesn’t exist! How could such a thing happen, and where did it disappear to?
In 1912 Alfred Wegener, the geophysicist who produced the continental drift theory, published a book detailing that three fourths of the Earths continental layer, the SIAL, is missing.
These facts came to light in the 1980’s, when a number of ships carried out extensive studies of the ocean bed in an attempt to locate new oil reserves and resources. The samples they retrieved from these expeditions revealed something extremely odd. They brought back SIMA from the ocean bed, not SIAL. Further studies on these samples revealed that these cooled lava samples were no more than 65 million years old.
In conclusion these findings would indicate that prior to 65 million years ago there was an even layer of SIAL covering our entire planet, just like all the other planets in our solar system. Then something happened which tore away three fourths of the Earth crust, revealing the hot SIMA and lava from the asthenosphere beneath. This material then cooled over time to form the new ocean bed as we know it today.
Another piece of important evidence that lends weight to what happened is the break up of the Pangaea, or continental shift, as published by Alfred Wegener himself.
When three fourths of the Earths crust was torn away, the remaining land mass was all in one chunk on one side of the planet (the Pangaea). Then over millions of years, our spinning planet forced this land mass to break apart and separate around the earth into a more balanced position, forming the continents we know today.
The above picture shows a text book impression of what the Pangaea looked like 225 million years ago. However as we will examine shortly, the top right section labelled the Laurasia, would fit more appropriately, if it were rotated clockwise 45 degrees. This would then fill the gap where the Tethys Sea is depicted.
You may also have noted that the above depiction dates the Pangaea back to 225 million years ago, not 65 million. However if you were to rotate the Pangaea 45 degrees as we have just suggested, then the Paleo-magnetic measurements that date the Pangaea back to 225 million years ago, would actually date Laurasia and Gondwanaland as being still together right up to 65 million years ago.
If the Earths crust had covered the entire planet up until 65 million years ago, and was then suddenly ripped away, this would certainly account for the samples taken from the oceans bed. What’s more, it would also coincide precisely with the sudden tilt of the Earth to 23.5 degrees, which forced the beginning of the seasons which we looked at, and the mass extinction of prehistoric life.
To lend even further weight to this theory, there is even more geological evidence that we can look at in order to piece together the various parts of the jigsaw puzzle, and find the answers we are looking for.
