Researchers in the School of Geosciences at the University of Sydney have developed a computer package that lets scientists record and study the Earth over geological time.

Their GPlates software, which they describe as “Google Earth with a time-slider,” contains powerful tools for modelling geological processes. Yet it is simple enough to use in schools or at home, and is freely available. By combining data on continental motion, fossils and sediments, for example, scientists can analyse changes in geography, ocean currents and climate over geological time.
