Ok so in sokka master toph bends a rock from space or space earth but katara rightfully points out if it's a space rock then it isn't from earth so shouldn't the name be changed to rockbending
No not really. "earth" is a generic term fr rocks and stone. so it still means the same thing.
I mean I guess so but even though its called earth bending there are multiple versions of it so "space bending" could be another version of it
What do you think?
