The earth consist of superthin crust (just like an onion skin) that is being moved by molten magma from underwater trenches. The materials moves out ward and deposits materials at a constant rate.
Proof of this is the big island of Hawaii.
There is a hot spot there and the ocean floor and the islands move northward at constant rate of 3 inches per year.
Some islands have moved northward several thousand miles away from the hotspot of the big island...
In 65 million years, Hawaii big island would be in Bering sea (near Alaska)
Every 6,000 years, much of the ocean floor is subducted; the area would be equivalent to that of the USA
Any application: it is a dynamic moving earth; and we have to aware of that and its dangers. These learnings give us a better understanding of the catastrophe.
