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 ...
Scientists have long understood that that can accelerate or slow the planet’s rotation — a trend that can shift over 10- to 20-year intervals. Right now, the core is temporarily causing the ...
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 ...
Scientists say the Earth's axis tilt has changed due to melting ice caps over the last few decades. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please call: 800-290-4726 ...
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.

Cases of true polar wander have occurred several times in the course of the Earth's history. [1] [2] It has been suggested that east Asia moved south due to true polar wander by 25° between about 174 and 157 million years ago. [3] Mars, Europa, and Enceladus are also believed to have undergone true pole wander, in the case of Europa by 80°. [4]
