Maggie's Farm

We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.

Tectonic plates

Photo and link via Vanderleun. Article here.


Photo is from the growing underwater rift area between the Eurasian and the North American plates.


Is the entire crust of the earth expanding, or is all of the plate separation compensated by subduction elsewhere?


Theories abound, but plate theory was considered crackpot just a few decades ago.

Dr. M. your spam just deep-sixed a posting.

Coincidentally, this posting on tectonic plates reminds me of a posting at Bookworm Room about one of our President’s recent malapropisms when he talked about a "Teutonic shift" instead of a tectonic shift": (Not to denigrate our President’s speaking style…)

QUOTE:
“Internationally, we’ve gone through a Teutonic shift in the Middle East that could have enormous ramifications for years to come.”

Teutonic shift, tectonic shift, seduction, subduction: the possibilities for wordplay are endless. Check out the wordplay at Bookworm Room.

Gringo,

Methinks, a visit from Teutons would right balm Arab Spring malady in Middle East about which el presidente is attempting to appear knowledgeable.

well, if the earth got bigger that would explain why Malthusian predictions of terminal overpopulation are wrong...
It's the perfect moonbat cure for their own flawed logic, add more flawed logic...

ahh planet Earth...your endless delights...reminds me of the Rhett Miller lyric: "blame it on the moonlight blame it on plate tectonics..."

Mark well the date on which you first heard of the expanding rift.

Within a month or two, another "science" clique will begin condemning all of us for having brought Earth to the brink of some sort of end-of-times Event through our selfish refusal to help stop AGS.

Fortunately, Anthropomorphic Global Swelling can still be stopped; unfortunately, time's running out fast. To stop AGS, we're going to have to send staggeringly colossal sums of money to the Scientists who are working on AGS, and to the Administrators who guide them. (All of the advertisements and commercials will have the correct International P.O. Box Number highlighted across the bottom. They're trying to make it memorable in its own right, something like "P.O. Box AlGore, USA", to make it easier for people.
