OT: Pangaea |
We've all seen animations that show how the great supercontinent
Pangaea broke up into the continents we know today. Here's a good
example:
http://piru.alexandria.ucsb.edu/collections/animations/Pangea.mov
Has anyone seen a similar animation that projects into the future, say,
500 million years from now? A computer simulation that extrapolates
from the known movements of Earth's tectonic plates with reasonable
accuracy?
There is some speculation that the current continents will once again
congeal into another supercontinent in the distant future, but I've
been unable to find confirmation of this theory.

I saw a science documentary on TV (PBS or Discovery, I think) that showed
exactly that ... as well as an article or two in Scientific American, over
the past few years.
According to computer models, the Earth's tectonic plate system seems to be
"oscillating", in that the continents drift apart, and then, at some point,
start to drift back together again. Through all this, the Atlantic
alternately widens and narrows, but never gets as large as the Pacific. The
other oceans and seas, such as the Indian, tend to form and shatter as the
land around them drifts about. Right now, the Atlantic is widening but,
according to the models, will eventually stop and then reverse. All this
takes many hundreds of millions of years, of course. So, the joke bumper
sticker "Reunite Pangaea", will actually come true...
That's the gist of the presentations I've seen. I can't give you citations
off the top of my head, but I'm sure the material is available out there,
once you figure out the right words and phrases for Google.

made the light shine upon us with this:

So if I wait a hundred million years, a ticket from NY to London could go
down considerably.

Or, you could simply walk there.

While not an animation, this is a pretty good article on the long
history of supercontinents on Earth.

Oh. Great. Just what I need. Another website with a black background
and red text. Don't these people have eyes?
Still, I guess it's good for a laugh.

I found this site pretty quickly on Google:
http://ve.ou.edu/weaver/plates/main.htm
Towards the bottom is an animation that takes the continents from Pangea to
the present day, and then to about 50 million years in the future (with the
present day positions marked in gray, so you can see the shift.) Below that
is a map of possible positions about 250 millions years in the future.
