 North America

The shock wave raised the Appalacian Mountains in the push off from Africa.  Central America unfolded from between North and South America.  Greenland and the Northern Canadian Islands broke away from North America as it moved west.  A trench formed when the Antilles was pulled off of South America.  Friction along the entire leading edge built major mountain chains and stopped all movement.



The Appalachians exemplify impulse mountains raised at the beginning of the Shock Dynamics event.  Folding of these mountains was caused by pressure from the shock wave initiated by the giant meteorite impact east of Africa.  This is borne out by a specialist in Appalachian geology who wrote, "maximum orogeny [mountain building] took place in a linear core belt... These rocks, and any floor on which they may have rested, were as if gripped and squeezed between the jaws of a giant vise, and at the same time heated up enough to become quite plastic and to stew in their own juice, in the fluids released as they transformed into mineral assemblages."  "...for me the vise is not a metaphor but a fairly exact model.  Thus the evidence of intense shortening perpendicular to the length of the chain, not only in the folded marginal belts but also in the central core belt, is too clear for me to doubt that there was not only confining but directed pressure, the greatest compressive stress being consistently directed roughly horizontally across the orogenic belt."  "Compression then relaxed, and the thickened crust rose isostatically to form mountains and has continued to do so ever since."  As a believer in Plate Tectonics, he could not find a mechanism in the crust that could do this, but imagined mantle convection must be involved.

Apparently there were already two large meteorite impact craters in the protocontinent before the Shock Dynamics event.  Though Hudson Bay opened up as North America moved, their forms and central peaks can still be seen.

The Chicxulub meteorite impact crater is on the northern edge of the Yucatan Peninsula.  The meteorite apparently struck at a low angle, leaving features similar to an oblique impact on Mars, imaged (below right) by the High Resolution Imaging Science Experiment camera on the Mars Reconnaissance Orbiter.  The arrow shows the direction of travel of the meteorites that formed both craters.  The Mars picture has been turned for the purpose of comparison, but the Chicxulub crater is oriented as it is on Earth, roughly south to north.

We would not expect a meteorite impacting Earth to be travelling south to north.  Comets and asteroids entering the solar system tend to align with the orbits of the planets in the plane of the ecliptic due to the pull of gravity.

Also, it is extremely unlikely that an object would ever collide with Earth while in an orbit perpendicular to Earth's orbit.  So what happened?  Plate Tectonics theory has no answer, but Shock Dynamics does.

Before the event, the Yucatan Peninsula was turned 90 degrees clockwise from the way it is now, folded in with the rest of Central America in the protocontinent.  The Chicxulub meteorite, travelling west to east, struck the protocontinent and made cracks in the continental crust.  When North and South America moved west during the Shock Dynamics event, Central America separated from Africa along those cracks, opening up to its current position in which the Chicxulub crater is oriented south-to-north.

Shock Dynamics theory explains what Plate Tectonics theory cannot.
