I was reading this article, and noticed this section:
At the opposite end of the plates, the presence of water underground changes how easy or hard it is for one plate to subduct beneath another in a plate collision zone, as was discussed at a recent AGU conference (link to session), 50 years after the AGU conference where Jason Morgan presented his theory.
I would like to explore a hypothetical scenario. Assume that the continents are in a Rodinia or Pangaea position (either one or both positions can be explored in this scenario). I understand that the current theory of plate tectonics says that the plates moved from the Rodinia and Pangaea positions to their current positions slowly over millions or billions of years. However, for this scenario, let's say these plates moved into their current positions in a year. What conditions (perhaps focus on the amount of water and pressure) would be necessary for this to occur in year? I would imagine it would need very extreme conditions.
In addition to this, what would the affect be from such conditions and movement?
