Today in Earthquake History

Today's Earthquake Fact:
The oldest rocks on Earth are found on land. Since the ocean floor is being continually regenerated as the continental plates move across the Earth's surface, the oldest rocks on the ocean floor are less than 300 million years. In contrast, the oldest continental rocks are 4,500 million years old.
