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.
