After the moon formed, due the proposed Theia off-angle
collision with the new Earth, it was vastly closer to its
parent planet; maybe 3 roche radii (?). Just how powerful
and high would the resulting tides been on Earth? I include
any oceans and tides within the solid (crustal?) Earth.
Would such tides have contributed greatly to any plate
tectonics and volcanism? Would this have contributed
to the ultra-hot and highly fluid komatiite lavas?
