Question

What's three pieces of evidence that Wegener used to support his theory ( Alfred Wegener’s hypothesis of continental drift states that the continents once formed a single landmass, broke up, and drifted to their present locations )

and why it is important to have several pieces of evidence when proposing a theory to describe phenomena like Alfred Wegener did.

Answer 1

In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
