Welcome to Gaia! ::

I might sound like I don't know anything, but this is giving me a headache.

All Earthbenders have the potental to bend metal, but only if they study the movements of Air and Water can they bend Sand, which is said to be more like the other two because of it's shifty nature. Now my question is this, do Earthbenders have two subs? I know that and Eathbender has to be touching the metal they're bending, at the moment, and thus they become vunerable as the metal acts as one big lightning rod to fire benders.

I never said the healing wasn't the sub of water I simply stated that unlike the other elements healing did not require years of training.

That's clearly proven in the north pole episodes.

Qoutes supporting:
Here the women learn from Yugoda to use their waterbending to heal. I'm sure she would be happy to take you as her student despite your bad attitude.

Go back to the healing huts with the other women where you belong.

No problem.

I don't necessarily agree with this. "Earth" is a general term for the minerals of the ground. Most of which are metallic or crystalline in structure. A rock may be a rock, but rocks are no different than any natural metal you'll come across. The only difference is that wrought metal has been shaped and tempered, but it's still made of the same stuff as any boulder an Earthbender can launch.

The variation of this concept is that though it's made of the same minerals, it's a far purer form and contains a great deal more of specific minerals per square inch than a random section of ground thrown at someone due to metallurgic principles. So I honestly don't see what the problem is with bending metal... sure it wouldn't be easy due to the sheer bending focus and severity needed to force wrought minerals to change their new forms, like bending a door or a wall...

But if it's between a hunk of metal or a boulder, both should fly quite nicely if you just need something to throw. Manipulating metal from its current form should be far more difficult than simple hurling exercises.

Anything with "Earth" meaning a solid amount of Carbon fuesed with something should be good. That is the possible explination why we don't see Earthbenders controling Bannanas, since the Potasium is calssified as a "Metal" or other things. I mean your average clod of Dirt has a high concentration of Carbon, and metals are purified of Carbon, wich is why it is logical for it to be harder to bend.

But this is my two cents, I get way too technical.

no, it's just no one's on anymore ^^
