Forks are so much easier to slide under an odd shaped rock that it is hard to describe. Since they are so much narrower they just easily slide under. Often just one tine can reposition a rock for easily grasping with both tines. Even embedded rocks can be popped out like a bad tooth usually. I've used mine a lot building my woods trails, and around the yard. If you can wiggle it with a tine, it will come out, and leave a much smaller hole than with a bucket, or even a backhoe.
