Still can be Wind Release. Momoshiki's Rinnegan turns red when he unleashed any jutsu, including the non-Rinnegan ones.

Momoshiki can use all the types of elemental jutsu, why not Earth Release? It rather looked like an earth technique. Not really anything new for an earth technique to manipulate the pre-existing rock against the opponent.

Again, Momoshiki demonstrated all kinds of elemental techniques during the attack on the stadium, including both Earth and Wind Release. I see no reason why he couldn't use them once more during the final fight. The forehead Rinnegan didn't seem to bear any function that the palm Rinnegan didn't have.
