Plate Tectonics Animations
These animations were originally produced for the US Geological Survey video Secrets
in Stone. They have been converted to animated gifs for web display.

Plate motions from 600 million years ago to today. (3.2 MB)
|
Map of world topography and oceans with plate boundaries,
and arrows representing plate vectors appear.
|
This animation begins with a world map, plate boundaries appear, and
plates are distinguished by color shades.
|
Beginning with a view of Earth with the continents in their present
positions, the continents move back in time to reunite as Pangaea,
are labeled, and locations of stratigraphic and fossil evidence
that Wegener used to
argue in favor of continental drift are added.
|
Beginning where the animation above leaves
off, the globe shows Pangaea reunited and
locations of stratigraphic and fossil evidence that Wegener
used to argue in favor of continental drift. The continents
break up and move to their present positions, carrying the evidence
with them.
|
Animation begins with globe showing Pangaea united, the continents
move apart to present positions. No labels are added in this
version.
|
The globe showing topography of continents and ocean basins,
followed by red dots appearing on Hawaii, Aleutians, and the
Rio Grand Rift, California.
|
Magnometer - A ship moves across the view, towing a magnetometer, magnetic stripes that the magnetometer 'sees' then appear superimposed on ocean floor.
|
Blue field with strip of magnetic stripes, then another stripe
appears that shows how this correlates with time before the
present.
|
A close-up showing mid-ocean ridge topography with magma chamber
below, which rises and new ocean plates spreads away from
ridge.
|
A close-up of a mid-ocean ridge showing normal and reverse stripes; magma
rises, and stripes move away from ridge. Good companion for
ridge topography version, above.
|
Same as animation two rows above, except it has stripes moving
away from ridge beneath surface topography, representing magnetic
stripes.
|
Begins with close-up of mid-ocean ridge with topography, normal
and reverse magnetic stripes appear, and arrows point, showing
which stripes are normal, then arrows point to which stripes
are reversed.
|
Porosity and vein formation.
|
Where are the world's energy-using urban areas? You can easily see them on this spinning globe shown at night.
