Why is Earth a Magnet? (Part Two)

EARTH MAGNETIC FIELDS, VOLCANOES, EARTHQUAKES and CLIMATIC IMPACTS. We’ve been wondering for a while if the hot spots, which are found around the Earth’s crust, are weak points in the earth's magnetic fields (or strong points?) The earth's magnetic field is changing rapidly and as it's also induced by the sun's magnetic field, which is also in a weak period, perhaps we will see an apparent increase in volcanic activity or the awakening of long dormant volcanic fields, such as the Garrotxa volcanic field in Spain or the Chaine du Puys in France? What seems amazing this year is the volcanic and seismic activity, in Italy, Tonga, Chile, Alaska, the Caribbean, Hawaii to name some areas. Read more [...]

Why is Earth a Magnet? (Part One)

Earth's Inconstant Magnetic Field.

Our planet's magnetic field is in a constant state of change, say researchers who are beginning to understand how it behaves and why.

Earth has a large-scale magnetic field. Solar wind is deflected away from Earth, protecting the atmosphere. Earth has a magnetic field, but obviously that is not what is really happening. So what is really happening? Read more [...]
