...potential payoff makes the risks seem worthwhile. The mid-Atlantic rift valley that the subs will probe is the place "where the earth's crust is created," says Chief U.S. Scientist James Heirtzler of Woods Hole. According to the revolutionary new view of geology called "plate tectonics," the earth's outer shell consists not of a single solid mass but of half a dozen or so giant plates on top of which the continents drift like extremely slow-moving ice floes. It was the gradual outpouring of lava from deep within the earth's mantle along...
Impressed by the apparent correlation between wobble and earthquakes, Columbia University Physicist James Heirtzler offers a different theory in the current issue of Scientific American. The prequake variations in the path of the pole suggest to him that the wobble is responsible for-rather than a result of-the earthquakes. Furthermore, he speculates, the wobble may also cause climate changes, mountain-building, and even the occasional reversal of the earth's magnetic field. But Heirtzler's theory still leaves wide open the question that Mansinha and Smylie believe they have correctly answered: What causes the wobble...
