The Part Of Britain That Rises And Falls Twice A Day

When you hear that a part of the coastline rises and falls twice a day, you surely think, "Yeah, that's the tides. The land is not falling, but the water is rising." And so that's what people thought of the rise and fall of the peninsula of Cornwall. But with precise modern measurements by GPS, we found that the land does indeed rise and fall in that area, in tune with the tides but not just in relation to where the waterline is. Tom Scott explains this anomaly.
