Researcher after new study said that the Moon plays a major role in maintaining the Earth’s magnetic field, including that the lunar action, overlooked till now, is thought to have kept the geodynamo active. Sun originated the radiation and charged particles, and Earth’s magnetic field protects us from it.
To keep the following magnetic field till the present day, the classical model called for the Earth's core to have cooled by around 3,000 degrees Celsius over the past 4.3 billion years.A team of researchers from the National Centre for Scientific Research and Universite Blaise Pascal in France recommends that on the contrary, its temperature has collapsed by only 300 degrees Celsius.
According to the researchers, “the Earth has a slightly flattened shape and rotates about an inclined axis that wobbles around the poles”
The Earth regularly gets 3,700 billion watts of power over the transfer of the gravitational and rotational energy of the Earth-Moon-Sun system and over 1,000 billion watts is thought to be convenient to carry about this type of motion in the outer core. This energy is enough to generate the Earth's magnetic field, which together with the Moon resolves the major paradox in the classical theory.
New model displays that the Moon's effect on the Earth goes well beyond merely causing tides.Published in the journal Earth and Planetary Science Letters.
