The continents move at about the same rate as your nails grow

The nails grow a little more than 0.1 mm per day or 3.5 millimeters per month on average, which is comparable to the speed at which America moves away from Europe: less than 5cm / year . For the Pacific Ocean, it is 10 cm / year, the speed of the growth of our hair. But unlike our nails, the spacing speed of the plates can vary considerably (and sometimes reverse): between 20 cm per year in the South Pacific and 1 mm per year in the south-west of the Indian Ocean.
