Red Shift, Expanding Earth and the Meta Model

I think part of the problem a lot of people seem to have with understanding how tectonics actually reshape the Earth is that they do not fully understand the subduction and volcanic inter-relationships. I'm not saying anyone has this totally figured out, but there is a lot of modelling that makes sense. Some plates push down into the mantle, and volcanic action forms new surface masses in other areas, and that alone would cause a great deal of shifting of continents over long periods of time. More importantly, it would reshape masses in enough ways that if things don't fit together properly, it still makes sense.

That said, I do agree there are flaws in the current models. I don't think that damns plate tectonics at all, but it certainly means the theories need some improvements.

The theories should be taken for want they are and the data should too. The data is quite clear that the ocean crust is subducted and the land mass is not subducted but moves around the surface like a ice burg in the ocean. All the land mass was formed in layers that can be observed all over the planet. It is data much older than the biosphere or life on Earth. Data in the layers indicates life began well after the land mass formed.

Water is quite a lubricant, and steam of massive scale could create conditions for subduction under the ocean that just don't work as well in drier areas of the Earth.

Dangus, The reason the ocean crust subducts and the continental crust floats is because the ocean crust is dense and the land mass is about 80% as dense. The light stuff stays up the heavy stuff goes down.

Oh I agree with that. I'm just suggesting that action of the crust occurs more easily under the ocean thanks to the vastly superior levels of lubrication, and the enormous weight of that lubricant also would likely do a lot of "helping" in the subduction process in many forms, be it steam, ice(near the poles perhaps?), or liquid water. If we look at where the most active vulcanism is, and where the worst earthquake activity occurs, I think perhaps we might be able to figure out some patterns regarding all that. I know some of that has already been done, but I suspect more can be.

I would also guess it's relative light mass is quite possibly part of the reason it stays "afloat" as you suggest, like an iceberg. That seems quite reasonable.

Hi Dangus, The ocean crust is a lot different than the land crust in several important details. It is denser, recycles at a rapid rate, and is composed of elements that the lighter continental crust has lost to an ocean that was different when the land formed. Floating continents were made from the same stuff ocean crust is made of but when the ocean was a lot different than it is now. So, everything has changed and it is not evolving since it could return to the way it was before the land formed. It makes a lot more sense-things always change and sometimes evolve.
