Quizplus · Accepted Answer

As you cross the Atlantic Ocean basin from North America to northern Africa, you are moving away from the Mid-Atlantic Ridge (where new oceanic crust is formed) and towards the African Plate (which is older). Therefore, the rocks get older as you move west to east, indicating an old-young-old age pattern. Choice D is the only one that matches this pattern.
