Plate spreading rate
The rate of spreading along the Mid-AtlanticRidge averages about 2.5 centimeters per year (cm/yr), or 25 km in a millionyears. This rate may seem slow by human standards, but because this processhas been going on for millions of years, it has resulted in plate movementof thousands of kilometers.
