Breakthrough Achieved in Explaining Why Tectonic Plates Move the Way They Do
Scripps Institution of Oceanography ^ | July 15, 2010 | Unknown

Researchers at Monash University and Scripps Institution of Oceanography identify movements of plate and plate boundaries; could substantially improve models of tectonic motion

Scripps Institution of Oceanography / University of California, San Diego

A team of researchers including Scripps Institution of Oceanography, UC San Diego geophysicist Dave Stegman has developed a new theory to explain the global motions of tectonic plates on the earth's surface.

The new theory extends the theory of plate tectonics - a kinematic description of plate motion without reference to the forces behind it - with a dynamical theory that provides a physical explanation for both the motions of tectonic plates as well as motion of plate boundaries. The new findings have implications for how scientists understand the geological evolution of Earth, and in particular, the tectonic evolution of western North America, in the past 50 million years.

The extension of unemployment benefits is sure to accelerate the movement of the plates to the same degree to which it has accelerated job growth.

Well, it looks like my graduate school theory of billions of subterranean hampsters has gone by the board.

Thanks for posting. Now I’ll have to find more to read on this.

THEORY.....

Just like Global warming

I would think that it is fairly obvious.

The whole planet is growing in size. Has been for billions of years.

That ‘growth’ causes earthquakes as well. If you get on GOOGLE EARTH and look at the DEEP OCEAN RIDGES, you can see the ‘growth lines’ on the seafloor.

Growing in size?

You mean like Popcorn?

Sounds like an overcomplicated explanation of the plates moving due to the convection within the earth.

tested hypotheses and theories are two different things. Just FYI.

Yes it is theory, but very well supported theory, unlike global warming. All non-experimental geology is theory based on circumstantial evidence. The evidence is heavily in favor of plate tectonic theory.

Are you a geosynclinalist?

There are matching subduction regions where the crust in pushed down (or goes down naturally and pulls the rest of the plate along) which eliminates sections of the earth's surface.

Theory and hard science are too often confused.

Interestingly enough, it was the son of Charles Darwin who came up with the “theory” that the moon was moving away form the earth an why.

He was wrong about why and how but today we know for a fact that the moon is moving away from the earth.

Dude! You can't just ask someone that on a public forum.

That's the sort of thing you say right before you absquatulate.

Well, it's not like that dissertation will see the light of day. I mean, someone signed off on it.

I think that I was able to impress the committee in other ways. Steven Schneider thought that it made sense.

But he thought you had to offer up a scarier scenario and replaced the hamsters with clowns?
