If Earth’s plates move as fast as our fingernails grow, that explains why we can’t sense their movement. Can you feel your nails growing? No, it happens too slow!
If we wanted to get an estimate of how far the plates will move in a week, we could try this experiment.
- Cut your fingernails tonight.
- Leave them to grow for a week.
- Cut again and measure the length of the cuttings after a week’s growth.
How could you use that data to estimate how far plates move in a year?
