Example of tectonic plates: Plates can move at about 2.5 cm per year, about the speed that your fingernail grows. Apart from the sudden movements that we feel during earthquakes, it is difficult to feel the continents move because we are moving at the same slow velocity as the continents. It is similar to being inside a car moving at 120 km
