All bending is just manipulating whatever's already there.

Airbenders maniplulate air, but since it's a gas, at high altitudes they have trouble.

Water is in every organic object, as well as being a landscape feature and in the air. All they really do is condense wator vapor, or in the case of plants, rip it out.

Earthbending is pretty straight-forward.

Firebending is more of an energy manipulation thing, so I think it's the second most pure bending form, the first being energybending. The fire, lightning, or heat is generated in the bender's body then channeled through their mouths and extremities. That's also why when a bender is tempermental or emotional the flames are wilder and larger, especially if they're a powerful bender.
