the difference is not subtle
in a proper carve: speed, high lean and the weight of the rider combine to engage the sidecut of the board. the camber gets turned inside out and you ride that rail of the edge. It feels like the board is making the turn, because it is. you use the pop of that camber to switch edges and on you go. a true carve track will be about 1 inch wide with a bit of an offset gap where the edge change happens. a skidded turn, which is often also needed, is pretty much not all of the above. (yes, i know all boards are not cambered, and that one can carve a rocker board)
trenching/eurocarving is a discipline in that the board for that is pretty much useless for anything else and that is what they do all day ,under the chair in a somewhat gay and irritating fashion statement.
carving is a technique, mixed with all the others to have a full, all mountain/freeride skillset
in my humble opinion.
