This is a FREE 10 slide powerpoint that introduces the concepts of continental drift and plate tectonics. It includes colorful pictures, powerpoint animations and a link to an online animation of global plate reconstructions. The slides include a short discussion of the evidence Alfred Wegener used to develop his theory of continental drift, namely: geographical fit of continents fossils match across oceans rock type and structure match across oceans ancient glacial features

Alfred Wegener (pictured here on the right) realised that many continents fitted together like reverse templates. This caused him to propose the theory of continental drift, which evolved into the ideas of plate tectonics.

This second sequence shows the continents drifting apart, in reverse, from 105 million years ago to 240 million years ago.

The Pangaea Pop-up - Michael Molina: The supercontinent Pangaea, with its connected South America and Africa, broke apart 200 million years ago. But the continents haven't stopped shifting -- the tectonic plates beneath our feet (in Earth's two top layers, the lithosphere and the asthenosphere) are still traveling at about the rate your fingernails grow. Michael Molina discusses the catalysts and consequences of continental drift.

Ron Blakey's maps of the paleotectonic evolution of North America. This shows the land 510 million years ago, progressing from there—reading left to right, top to bottom—through the accretion and dissolution of Pangaea into the most recent Ice Age and, in the final image, North America in its present-day configuration.

During the Permian era (around 300 million years ago) the strange slow dance of Earth’s tectonic plates brought together all the world’s major landmasses into the supercontinent Pangaea.

Plate Tectonics map with legend. This would be a great map to use when we cover Pangaea. This maps shows not only how the continents used to be, but also how they moved. Students could create their own map in class after the lecture.
