According to Youjun Zhang, the Earth's inner core is covered with A. a thick layer of rock B. icy water crystals C. tiny particles of iron D. the snow we see in winter2. What plays a great role in forming the magnetic field around the Earth? A. The outermost layer. B. The ...
The magnetic field amplifies the iron of mantle and a kernel of the Earth. As a result of action of a radial electric field the electrons will flow from the center of a kernel in a layer of an electric charge. The central part of a kernel represents the field with a positive electric ...
This is because the magnetic field(磁场) of the Earth "protects" us from the "wind".At the North and South Poles, however, some particles may get in and meet with the Earth's air. Then, the particles get "excited" and have a "dance" with the air. So, we can see the moving aur...

The magnetic field of the Earth has global meaning for a life on the Earth. The world geophysical science explains: - occurrence of a magnetic field of the Earth it is transformation of kinetic energy of movements of the fused iron in the liquid core of Earth - into the magnetic energy; ...
Similarly, the variation in snow pile size-lighter in the eastern hemisphere and thicker in the western hemisphere-explains the more rapid pace through the top inner core.5 It not only forms a protective magnetic field (磁场) around the Earth but helps change the direction of solar winds. ...
When placed in any location on Earth, the needle aligns itself with the Earth's magnetic field, pointing towards the magnetic north. - This behavior of the compass indicates the presence of a magnetic field around the Earth. The fact that the compass consistently points north, regardless of ...
Claims that Earth's magnetic field is responsible for climate change are widespread online,but scientists say the theory has no basis.(但这些地磁事件是造成极端天气、物种灭绝甚至灾难的原因吗?地球磁场导致气候变化的说法在网上广为流传,但科学家表示,这一理论没有根据)以及划线词上文It's not that we'...

Deep in the cen-ter of the earth, there is a very hot liquid(液体). As itmoves around, it develops magnetism. It surrounds theearth with a powerful magnetic field. If the earth's mag-netic field did not exist, the sunshine would easilyburn us.Magnets can attract certain kinds of ...
