The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
In an eye-opening study, researchers have discovered that human activities, particularly groundwater pumping, are causing a significant shift in Earth's physical orientation. The findings, now ...
New research shows that persistent groundwater extraction over more than a decade has shifted the axis on which our planet rotates. Humans pump so much groundwater that Earth’s axis has shifted ...
From 1993 to 2010, the earth is believed to have tilted 31.5 inches east, according to the study, which was published by Geophysical Research Letters. This is because of how much groundwater was ...
In Maps of the Ancient Sea Kings (1966) and The Path of the Pole (1970), Hapgood proposed the hypothesis that the Earth's axis has shifted numerous times during geological history. [2] The Path of the Pole was meant as a replacement for The Earth's Shifting Crust after corrections were suggested to him.
Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the gravity of the Sun, Moon and other bodies.
The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the Earth’s tilt of roughly 31.5 inches. The ...
Cases of true polar wander have occurred several times in the course of the Earth's history. [7] [8] It has been suggested that east Asia moved south due to true polar wander by 25° between about 174 and 157 million years ago. [9] Mars, Europa, and Enceladus are also believed to have undergone true pole wander, in the case of Europa by 80°. [10]
