Answer:
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.

Wegener used the similar mountain ranges and areas made of certain types of rock found in Africa and South America as evidence that these two continents were once connected because-
- In his continental drift theory, Wegener suggested that the similar mountain ranges that were formed in Africa and South America that was once connected were later separated due to continental drift.
- The same type of rocks that were formed at the same geological time is now found in both Africa and South America due to continental drift.
