How does Glossopteris provide evidence of Gondwana and continental drift?
Glossopteris fossils are found on different continents that are far apart from each other today.
How did Wegener use fossils to support his continental drift hypothesis?
The same fossils were found on several continents that fit together like puzzle pieces.
How did Wegener explain why the same fossils were found on continents that have different climates today?
The continents had the same climate in the past and drifted apart to their current locations.
Which of the continents would not support Glossopteris growth today?
Antarctica
