I realize that this may venture a bit off the core topic, but you did mention in Episode 17] that the moon causes some mountains to change height by up to 30cm in line with the tidal surge caused by the moon [oh yeah, and the sun], so what I would like to hear about is thy effects of this much force flexing our planets techtonic plates and this contribution to earthquakes, volcanic eruptions etc etc.
