the age of the continents the shape of the continents the thickness of the continents the composition of the continents
I gave my students this multiple choice question: Which of these was used by Alfred Wegener as evidence that Earth's continental landmasses had drifted apart over time?

Only one answer is correct among these 4 choices:
- the age of the continents
- the shape of the continents
- the thickness of the continents
- the composition of the continents

Could you tell me which one is correct?

the shape of the continents
