Alfred Wegener: Great Minds

The video discusses Alfred Wegener, a scientist who proposed the theory of continental drift. Despite initial ridicule from the scientific community, his ideas were later validated with the discovery of tectonic plates. Wegener's diverse interests and his evidence for continental drift, such as matching fossils and geological formations, are highlighted. Although he faced criticism and died before his theory was accepted, Wegener is now recognized as a pioneering scientist.

What was one of the incorrect ideas Wegener had about how continents moved?

• They were pushed by ocean currents
