A very interesting article that I found on Neal Adams website
First… it’s important to understand that this is the most profound disagreement in all of science in a century and a half… and, even so, it is the tip of the iceberg, the ramifications of this disagreement will change everything we know in science, top to bottom.
To begin with basic stuff.
All science knows…
The earth has two crusts. One…the mostly basalt lower crust or the oceanic crust which is 2 – 4 miles deeper down than the higher upper continental crust. This lower crust, essentially covers the Earth. It … this crust is being made daily at rift cracks that snake around the earth’s mid- oceans. But how could all these rifts continually spread apart…without the Earth growing? Ah….that is the question….isn’t it?
Sitting on or “in” and “as part of” the oceanic crust is the second higher upper crust or the Continental Crust rising for the most part out of the water. It is made mostly of granitic rock, which is 2.5 times the weight of water.
Some edge area of the Continental Crust or Plate dips into and under the sea level of the ocean. This area is what we call the Continental Shelf. So as you go out into the ocean and the water gets gradually deeper … that is the Continental Shelf. At a given distance out into the ocean the ocean floor suddenly drops off and goes down like a plummet… 2 ½ to 4 miles to the deep ocean floor, where we find the second lower crust, the Oceanic Crust made mostly of basalts which are 3.0 – 3.3 times the weight of water. So to make it visually clear, if you took the water away what you would see as you go out into the ocean a distance is, the Continental Shelf would suddenly drop away and down like a ridge in Arizona., except it would go straight down for two to three miles, as if it was suddenly broken off. The other side of that broken off ridge is across the ocean thousands of miles in Europe, or Africa and west to Australia and Asia.
How did the two sides of this higher crust spread apart?

Here's a video of the whole argument - it works for me. I never did buy into the pangea theory and now here is a refreshing view of how things happened. I like it. Comments please?
