The above map showing earths tectonic plates and where they converge, subduct, diverge and slip strike, tells a story of the past. According to expert opinion, there would have been no “teeter-totter” isostatic effect from the weight of glacial ice that covered huge swaths of the North of Eurasia and North America. I seriously question this. I agree with some of what they allege— that there older portions of the Pacific Plate are denser and so subsiding beneath the lighter North American plate, butt the teeter-totter did and is still occurring. This is also why the Pacific Plate could so easily subduct under the North American Plate— pushed by the Antarctic Plate that was also much more laden with glacial ice in such a way that the plate had “flattened” out more, an effect that has since subsided with the great loss of Glaciers there, and with the subsiding and regaining a bit more of its natural curvature, it then began to pull away from the Pacific Plate at its most southern end. In the meantime, the Pacific Plate is still subducting under the North American Plate, butt this will also soon come to an end as the Plate here regains more of its natural curvature. Also compounding the subduction situation is the immense weight of water at the deep trenches in the northern and western portions of the Pacific Plate. According to AI, the expert opinion is that the added weight of water on the Pacific Plate would not cause it to sink further … WHAT?! Are you kidding me, THAT makes no sense whatsoever!!
