The presence of similar fossils on different continents, indicating that these continents were once joined.

Front

How does climate evidence support Continental Drift?

Back

Fossils of plants and animals found in climates that are now different suggest that continents have moved from their original positions.

Front

Back

Evidence of past glacial activity found in currently warm regions, indicating that continents have shifted over time.
