The Part Of Britain That Rises And Falls Twice A Day

From Tom Scott.

Cornwall rises and falls by a few centimetres, twice a day. I didn’t believe that when I read it. In this video: "ocean tide loading": why, how, and does it actually matter?

Thanks to Prof. Peter Clarke, who is a professor of geodesy, not geodisy. Apologies for the typo!
