(DESCRIPTION)
From space, the Earth spins.
 
Text, Looking down on Earth from space, it's easy to imagine the continents as puzzle pieces.
 
We get closer. A map of earth. Text, The east coast of South America appears to fit nicely into the southwestern coast of Africa. Several arrows drag the two continents ever closer. A man's face appears in black and white beside a series of maps that bring the continents together into one.
 
Text, In the early 1900s, meteorologist and polar researcher Alfred Wegener realized the same thing.
 
Red pin points placed on India and Antarctica. The locations turn yellow and a dash connects them. An animal appears atop the map. Text, He read scientific papers that listed identical fossils found on opposite sides of the oceans.
 
North America highlighted. Text, He also discovered that large-scale geologic features like mountain ranges on different continents closely align when the two contents were brought together.
 
The map disappears and Alfred Wegener's portrait shrinks. Text, Wegener's Pangaea. Wegener suggested that the continents were once a large mass, now called Pangaea, that subsequently broke into separate continents that drifted apart.
 
His portrait disappears. Text, Continental Drift. In a time lapse, the continents separate then merge into the locations we know today.
 
Text, In the 100 years since Wegener first proposed his theory of continental drift, scientists have learned much about how Earth's tectonic plates move.
 
That plate movement generates earthquakes, volcanism, and mountains.
