You should read more of the Avatar Wiki pages.

First off, it's stated that all Air Nomads are born as airbenders because of their high spirituality. Therefore Tenzin, as the son of Aang, would be most likely an airbender.

Second, the Avatar is the spirit of the planet incarnated into a human form. Therefore he/she has the ability to master all 4 elements.

I can't explain how children inherit their parents' bending abilities, though.
