Dynamic Earth - the Story of Plate Tectonics
Jacquelyne Kious, Robert I. Tilling
the early 1960s, the emergence of the theory of plate tectonics
started a revolution in the earth sciences. Since then, scientists
have verified and refined this theory, and now have a much better
understanding of how our planet has been shaped by plate-tectonic
processes. We now know that, directly or indirectly, plate tectonics
influences nearly all geologic processes, past and present. Indeed,
the notion that the entire Earth's surface is continually shifting
has profoundly changed the way we view our world.

Plate Tectonic Reconstruction Service
This is the platetectonic reconstruction service. In this section you can
calculate platetectonic reconstructions of any age back to 150 My. Please
read the reference
information for more info on how these maps are calculated and what data
is used. There's also a reference you might want to cite if you use one of
these maps for a publication. An animation
(330 kb) using 5 my timesteps is available too (this is a new one, the old
on is still here).
Be aware it might take a while to download. The rotating earth above shows a
65 My reconstruction in an orthographic projection.
For more information about
how to use this mapping system, consult the manual
page or the links in the form. For other www-sites with plate tectonic
information, look here.
If numerical ages don't mean anything to you, visit the timescale
at the UCMP in Berkley.You can get interesting information on any
geologic era there.

The goal of the PALEOMAP Project is to illustrate the plate tectonic
development of the ocean basins and continents, as well as the changing
distribution of land and sea during the past 1100 million years.

History section of this website are full-color paleogeographic maps
showing the ancient mountain ranges and shorelines, active plate
boundaries, and the extent of paleoclimatic belts.
Earth's continental landmasses, upon which we live, may be thought of as
ships drifting upon a sea, propelled wherever the currents take them. This
slow voyage of the continents has reshaped the face of the Earth throughout
have investigated the theory of plate tectonics (which states that the
Earth's crust is made of several plates, each moving independently of the
others) for many years. Studies by NASA and radio astronomy sites around the
world support this theory.
