11. The oldest rocks on Earth are REALLY old - about 4.6 billion years old - but all of the oldest ones are found on land and not in the ocean. Around the mid-ocean ridge, the rocks are very young (only 9 million years old). Why is there a difference in the ages of rocks on land versus in the ocean? A. Convergent boundaries in the ocean create new oceanic crust, so that's where the newest rocks will always be found.
B. Transform boundaries in the ocean create new oceanic crust, so that's where the oldest rocks will always be found.
C. Convergent boundaries in the ocean destroy oceanic crust, so that's where the oldest rocks will always be found.
D. Divergent boundaries in the ocean create new oceanic crust, so that's where the newest rocks will always be found.
