In the study of the Earth's interior, magnetic field data is also used. How does the Earth's magnetic field help in understanding the Earth's interior? A. It has no relation to the Earth's interior structure. B. It can only tell us about the surface temperature. C. Changes in the ...
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquidironin Earth'souter core, a phenomenon called the geodynamo. Despit...
Professor: Okay, keep in mind that solar wind is electrically charged, which means that it interacts with the magnetic field as electromagnetic theory tells us.Okay, how does it interact?Earth, magnetic field deflects most the solar wind, makes it flow around the earth without getting very clo...

Does the magnetic repulsion of solar ions slow the earth’s rotation at all? Or is any deceleration due to this resistance imposed only on the iron convectional flows within the earth? Where do the solar ionized particles come from? Are they ejected from the fused elements within the sun, ...

s magnetic field at the time they are formed. Analysis of the crystals showed that, at their point of formation, the Earth’s magnetic field was the weakest ever recorded — some 30 times weaker than both the current magnetic field intensity, and that measured from similar crystals formed ...

Some animals can sense the earth's magnetic field (磁场),while humans can't.This magnetic field guides a certain kind of fish when they swim a long way to a place and then back.How can this kind of fish do that?It is still a mystery.Scientists have no good answers...
But don't worry, X-rays can't penetrate from outer space to the Earth's surface. Read more in How X-rays Work. Gamma rays: Gamma rays have the most energy and shortest wavelength of the entire spectrum. Nuclear explosions and radioactive atoms generate these rays. Gamma rays can kill ...
