[Avatar: The Last Airbender] Are Earth-Benders creating matter?

They regularly throw up great pillars of rock into the air. Are they displacing existing rock, creating fresh rock, or something else?

They do not create rock otherwise they would not need the rocks as a source.

They move it around. The great big pillars come from the fact that Earth tends to go pretty deep so they have a lot to play with.
