From what little I understand, it's actually largely just really stupid stuff like grit and dust eroding the aerodynamic surfaces of the blades. No one bit of grit does a huge amount of damage, but those things are out in the weather all day every day, and that takes it's toll...
In seriousness, yeah, I don't doubt it. A bit like how most of the wear that appears on ship propellers actually comes from air bubbles that they create. (Cavitation)
