hot spots on ocean floors seismic activity along plate boundaries sediment buildup on continental slope marine fossils found on land masses
I gave my students this multiple choice question: Which of these provides the best evidence that the distribution of Earth's oceans has changed over time?

Only one answer is correct among these 4 choices:
- hot spots on ocean floors
- seismic activity along plate boundaries
- sediment buildup on continental slope
- marine fossils found on land masses

Could you tell me which one is correct?
