Typical rates of sea-floor spreading are appoximately

Typical rates of sea-floor spreading are approximately 5 cm per year

Sea-floor spreading is a process that happens at the mid-oceanic ridge where a divergent boundary is causing two plates moving away from one another resulting in spreading of the sea floor. To calculate the spreading rate of one side of a mid-ocean ridge by dividing distance by time (Distance/Time = Rate) The typical rates of sea -floor spreading are approximately is 5 centimeter per year.
