I thought the tides question was a bit flawed/ambiguous, despite knowing which of the answers they were really looking for. "Which of these is the main way that ocean tides are created?" Are 'tides' defined as the tidal bulge caused by the moon, or the harmonic rising and falling of water levels caused by earth's rotation relative to that bulge? Would we (laypeople) even recognise there were ocean tides if earth's rotation was somehow slow enough for the moon to be geostationary? The bulge would still be there, but without the earth's relative rotation to the moon the sea level doesn't go up and down any more (ignoring the smaller tides from the sun).
