What would a piece of the ocean floor look like if raised to surface level and left for a few thousand years?

My world is basically the surviving chunks of an exploded planet (there's a little more to it than that but that's the important part for the question, ignore any issues of gravity etc.) and while trying to come up with geography and interesting locations I realised that some of those chunks would originally have been on the ocean floor.

The question is pretty simple, would a chunk of the ocean floor (minimum size something like France or Spain up to the same size as Canada, China or similar) dried out and left for a few thousand years to grow vegetation etc. have any interesting or defining features?
Or would it just look like any other normal landscape?
