Wegener thought the continents moved because they looked on the map as if they were once connected in a "puzzle". He envisioned that the continents moved but the outlines remained.
Alfred Wegener proposed the theory of continental drift, suggesting that the continents were once joined together in a single landmass called Pangea and have since drifted apart to their current positions on Earth's surface. He believed that the continents moved slowly over time due to the process of plate tectonics.
Alfred Wegener proposed the theory of continental drift in the early 20th century. He observed that the continents appeared to fit together like puzzle pieces, particularly along their coastlines. Additionally, he noted similarities in rock types, fossils, and ancient climate patterns across different continents. This led Wegener to suggest that the continents were once joined together in a single supercontinent, which he called Pangaea.

Alfred Wegener proposed the theory of continental drift because he observed evidence such as similar geological features, matching rock layers, and identical fossils on continents that are now widely separated. Wegener suggested that these observations could be explained by the continents drifting apart over millions of years.
One piece of evidence that led Wegener to propose the theory of continental drift was the observation that the coastlines of Africa and South America appeared to fit together like puzzle pieces. This suggested that the continents were once joined together and had subsequently drifted apart.

Wegener's theory that the continents slowly moved over Earth's surface became known as the theory of continental drift.
He could not explain how or why the continents moved.
because he didn't know how the tectonic plates/continents moved
volcanos
An earthquake.

Alfred Wegener proposed the theory of continental drift, suggesting that the continents were once part of a supercontinent called Pangaea that broke apart and drifted to their current positions due to the movement of the Earth's tectonic plates. He suggested that the continents "plowed" through the oceanic crust as they moved.
