WebThe Chandler wobble or Chandler variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, which was discovered by and named after American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth's surface and has a period of … WebEarth's axial tilt actually oscillates between 22.1 and 24.5 degrees. The reason for this changing obliquity angle is that Earth's axis also wobbles around itself. This wobble motion is called axial precession, also known …

WebMay 19, 2024 · The Earth’s spin axis is the figurative line about which the Earth rotates. The poles, north and south, are situated at either end of the spin axis. By contrast, the magnetic poles — the ones you can find using a compass — are usually offset from the geographic poles, and their location shifts with the magnetic field.
WebApr 8, 2016 · Polar motion refers to the periodic wobble and drift of the poles. It’s been observed for more than 130 years, but the process has been going on for eons driven by mass shifts inside the earth as well as ones on the surface. For decades, the north pole had been slowly drifting toward Canada, but there was a shift in the drift about 15 years ago. green fly bug sprayWebJul 15, 2024 · July 15, 2024 / 3:13 PM / CBS News.
