[Ostanes]

I don't understand your logic on this, Ostanes.

If anything disappeared in the depths of the sea, I would consider it to have "sunk." That seems to be compatible with the definition of sinking.

Disappeared and sunk are two different words and have two different meanings.

If Plato had wanted to say sunk instead of disappeared surely he could have.

However, he did not do so.

Atlantis, if it existed, was not a continent, but uplifted oceanic plate (likely from convergent compression -- two tectonic plates colliding).

Tectonic plates are imaginary and do not exist in physical reality, and, if they did exist, it would be impossible for them to collide since there is no mechanism for them to do so.

In actual fact the mantle is cold and it's rigidity increases with depth, because otherwise seismic wave velocity wouldn't increase with depth.
