We have proof of his meticulousness in that we possess his personal copy of the first edition of his book “The Formation of Continents [...] elements in the Earth’s crust. He called one of them sial and the other sima. Wegener assumed that the oceans were composed of a heavier material than the continents. He thus presumed that the lighter continents [...] continents float on the heavier subsurface, like ice floes on the water. That was the core of his idea! It was associated with the concept of so-called isostasy. This says land bridges or the like couldn’t come

A good example for this development is the North Sea, were more than 80 % of the coastline is already artificially protected.
