Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.
latitude: Latitude is the geographic coordinate that specifies the north-south position of a point on the Earth's surface. South Pole: The South Pole is the southernmost point on the Earth, lying diametrically opposite the North Pole. 在这一部分,...
The calculations used long-term data on the motion of the geographic North Pole with intervals between readings of 0.05 years, data on the components of the angular momentum of the atmosphere, and information on the appearance of global jumps observed at all magnetic observatories of the globe. ...
National Geographic's corporate-corrupted war on REALITY: how a once-upstanding mag now betrays humanity to push toxic poisons of advertisers4/8/2015 - The cover of this month's National Geographic magazine is causing some major controversy among the cognitively aware, as this once-upstanding and...
I was told today by my physics professor that the Earth undergoes magnetic pole reversals, some of the evidence being molten rocks with magnetic properties on Earth orientating themselves towards a different north pole which points towards the north pole being different in the past. He said that...
The moon generated a surprisingly intense magnetic field until at least 3.56 billion years ago, 160 million years longer than previously thought, a new study reports. These findings could shed light not just on the magnetic field of the moon, which is now extremely weak, but on that of aster...
Palaeomagnetic data imply that the Proterozoic geomagnetic field approximated a geocentric axial dipole, hence palaeolatitudes represent geographic latitudes. The Cryogenian glacial environment included glacier-free, continental permafrost regions with ground frozen on a kyr time-scale, aeolian sand-sheets, ...
that plates now move at speeds and trends quite similar to those of the geologic past (based on magnetic anomalies and subduction zones age constraints), confirming the existence of a sort of “tectonic equator” inclined about 30° with respect to the geographic equator (Crespi et al., 2007...
(2013) showed that at present, the dipole is very axial, whereas with increasing age the dipole axis substantially deviated from the geographic pole. The symmetry of the early time-average magnetic field highly correlates with the symmetry of the CMB heat flux heterogeneity, exhibiting magnetic ...
During the 1950s, paleomagnetic studies, notably those ofStanley K. Runcornand his coworkers in England, showed that in the latePaleozoic Erathe north magnetic pole—as reconstructed from European data—seems to have wandered from a Precambrian position near Hawaii to its present location in theAr...
