Atlantis Sunk?

Want to know what happened to Atlantis? Maybe it just simply sunk beneath the waves like Plato said.

Scientists have found a large , continent sized, slab of ocean floor sinking into the magma beneath the earths mantle. It is this sinking of solid land that causes some of the volcanic activity we see on the surface. There may be more than one slab of solid land sinking into the center of the earth. This is just the first one that they have found.
