The Earth's crust consists of multiple, rocky plates that move up, over, and under each other while being carried on portions of the Earth's interior mantle. Imperceptible over human lifetimes but dramatic over eons, the movement of the continents, Continental Drift, is one of the most fundamental of geological processes. It influenced the earliest forms of life to begin evolving on this planet.

A newly developed interactive map now allows anyone to view different eras from today's existing geography back through the previous one billion years of changes. It was developed by Ian Webster, an experimental software programmer at Google, and shows the constantly shifting surface of the Earth over the last 750 million years. Webster applied plate tectonics and other mapping tools, to illustrate how the continents changed over this vast time-line.

Put your home location into the map's coordinates and watch the geography change for yourself.
