Polflucht (from German, flight from the poles) is a geophysical concept invoked in 1922 by Alfred Wegener to explain his ideas of continental drift.. The pole-flight force is that component of the centrifugal force during the rotation of the Earth that acts tangentially to the Earth's surface.
Continental drift is a highly supported scientific theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics , which studies the movement of the continents as ...
The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well.

Alongside the constellations that have awed humanity for millennia, an errant tool bag is now orbiting planet Earth after wandering off during a spacewalk on the International Space Station (ISS).

Baron Kelvin got the age of the Earth too short. The concept of Earth crust and mantle. Airy-Heiskanen isostasy model instead of the Pratt-Hayford model. Thrust faults had to be accepted. The expanding Earth and the contracting Earth concept had to be given up. The shifting and evolution of knowledge and concepts, were from:
The cast and crew traveled to the Andes mountains to shoot the movie. Bayona told THR that his cast and crew traveled several times to the Andes to shoot the movie.
