    Wait what. I thought Wegner's theory is in the Physics spec, not the chemistry one. Wegner's theory was that a long time ago, Earth was one big continent. This means that the plates would have to move for that to happen and subduction sort of shows that the plates are moving.

    Anyways... the question you gave was quite peculiar.

    One of the reasons why Wegner's theory was not accepted at the time was because his theory didn't also explain how the plates moved. (since no one knew about tectonic plates and subduction). Therefore I don't think his theory really explains subduction.
