Well, the title says it all. I was wondering if you could destroy elevated terrain. Does it work like blocking?

You cannot destroy Elevated Terrain. While it would be kinda cool, it can't be done.

It'd be ridiculously cool for the purposes of taking out Stealthed snipers... Someone in an object on a building corner, can't see him, but just blow up the building corner and let 'em fall. Sadly, that's just a little too good, considering an attack roll wouldn't even be needed.
