Answer:
The oldest rocks of the oceanic crust are found in deep ocean trenches far away from active mid-ocean ridges.
Explanation:
Beginning in the late 1940s, oceanic expeditions continued to map the Atlantic ocean floor using new equipment and collecting thousands of rock samples. These works made it possible to map a gigantic system of submarine mountain ranges, called meso-ocean ridges. By perfecting the method of dating rocks, scientists have been able to determine the true age of seabed rocks. They found that the closer to the mid-ocean ridge the rocks were much younger than imagined, while rocks close to the continents were increasingly older, thus corroborating the Continental Drift.
