The mid-Atlantic ridge runs north-south through Iceland, the Azores and Tristan da Cunha. New sea floor rock is being pushed up and moves outwards (westwards on the west side, eastwards on the east side) at about 2 cm. a year. So the newest rock is in the middle. As you move away towards either the Americas or Europe and Africa, the rock gets older. When all this started, the Americas and Europe and Africa were one continent. Ever noticed how their coastlines fit like a jigsaw? The edges of the continental shelves fit even better and different mineral deposits on each side match up.

The age of the rocks would get older as you move away from the mid-Atlantic ridge (or any divergent plate boundary). The newest/youngest rocks are formed at the ridge, and move outwards.

It would get older.
The Mid-Atlantic Ridge is a division between tectonic plates where new ocean floor is forming and spreading outward. This is also causing the Atlantic Ocean to grow.
