How do you know the ages of the ocean floor near a mid ocean ridge?

Answer 1

It is all to do with the magnetism or the rock, because if you know about the curie point then it is all clear because when the liquid basalt comes up into the ocean, it takes time to become solid, and when it becomes solid, all of the magnetic particles have pointed in the correct position to the current position of the poles. This means that scientists know where the plea were at at a particular point in time and the rock matches up to replicate this, thus then being able to tell when that particular rock was created. hope this helps
