| 1445609 | 2018-02-14 07:47:00 | Well by subtle I meant gradual and not perceptible, ie it does not suddenly lift vertically in a way that we can notice. The earths Diameter is approx 12742 km, divide that by 384mm (assuming that's correct I didn't check) and we see that the land surface of earth is distorted by a factor of approx 1 in 33.18 million when the moon passes overhead. That fits my personal definition of subtle and negligible quite well. I tried to convert that to a % but my calculator doesn't go that small. | dugimodo (138) | ||

Yes. but expressed as a percentage of a typical oceanic tidal variation it is around 10%, not negligible in those terms. |
