8. Use the magnetic reversal time scale and the cross section of the Mid-Atlantic Ridge to calculate... What is the age of the ocean crust at \( \operatorname{spot} \mathrm{A} \) ? Based on the distance between the oldest "Gilbert" interval, what is the overall spreading rate (how fast are North America and Africa moving apart)? What is the overall height of the ridge from the ocean floor near letter B to the the highest peak along the edge of the rift valley in meters?
