 This theory was proposed by Alfred Wegener, a German scientist about 100 years ago.  He hypothesized that the continents were not always in the same.

The idea that plates move is not a new one. As far back as 500 years ago, map makers noticed something curious. They saw that the east coast of South America.

Presentation transcript:

How Do we know we’re moving? Alfred Wegener was one of the first to propose the theory of continental drift. While pondering the similarities between the coastlines of South America and Africa, Wegener came up with an idea: What if the continents were once all connected and just drifted over the years? It is this German man to whom we credit with the proposal of the theory of Continental Drift

A long, long, long time ago…in a land really close by…
