Map of Oceanic Crust Ages in the Atlantic

This map shows the ages of the crustal rocks that make up the floor of the Atlantic Ocean. Red represents the youngest rocks; the deepest red marks the Mid-Oceanic Ridge, where continental plates are pulling apart and new crust is being formed. Older rocks are yellow, green, and blue: the deepest blue rocks, along the coastlines of Europe, Africa, and the Americas, are Jurassic in age, showing the time of formation of the Atlantic Ocean.
