The early Earth, we can safely assume, did not start out cracked like this egg from its pristine beginnings.
Scientists now agree that the early Earth featured just one original continent named ‘Pangaea’, reminiscent of Chinese history’s ‘Panku.’ Historians and geologists have no clue what actually hit the Earth’s crust, or how the upper layer of 8 km thick oceanic crust and 35-60 km continental crust got cracked, nor why its fragments or plates then began to drift apart from each other, other than labeling it ‘plate tectonics & subduction’. That’s about as good an explanation as blaming “why there are murders” on “violence.” It does not explain what cracked ‘Pangaea’ in the first place, which would also indicate the real cause of why the continents drifted apart!
This article aims to try to solve this foundational mystery: “Why and how did Pangaea’s crust crack!”
