Following is a basic overview of my expansion / contraction model. It does not deal with oceans, atmosphere or the interior, simply the crust.

It is built on most of the basic facts, and interpretations thereof, established by contemporary plate-tectonics. It differs from the older 'Expanding Earth' models in the main pattern of continent movement that it suggests. Key to this pattern is the three plates of the Central and South American sea-beds, and the idea that they act as a 'hinge' which pushes the two American continents apart to almost 180 degrees, their land-masses having once been folded back and joined along their west coasts ( effectively closing the Pacific Ocean ).

The three plates in question are the Nazca, Cocos and Caribbean plates.

As you will see this concept is supported by the basic information about the Earth's crust, including its magnetic field ( although it offers an alternative interpretation of certain compressional areas ). It runs contrary to present plate-tectonic models, which are made on a constant diameter, and resurrects a question raised by the earlier expanding and contracting Earth models - what is going on inside to cause expansion?

I have also introduced a concept which I refer to as 'mirror-plating', which you wll find in section 9 through 15.

But first let me begin with the object which I 'found' via these plates, and which led me to the overall hypothesis of this site.
