[quote:Simple27:MV8yMzkxMDE5XzU1OTU4MDQ3X0E4NTUyNjdB] [quote:joinca:MV8yMzkxMDE5XzU1OTU3MDQ4XzYwODkyQkJE] [b]The Moon thought to play a major role in maintaining Earth's magnetic field [/b] The Earth's magnetic field permanently protects us from the charged particles and radiation that originate in the Sun. This shield is produced by the geodynamo, the rapid motion of huge quantities of liquid iron alloy in the Earth's outer core. To maintain this magnetic field until the present day, the classical model required the Earth's core to have cooled by around 3,000C over the past 4.3 billion years. Now, a team of researchers from CNRS and Universite Blaise Pascal1 suggests that, on the contrary, its temperature has fallen by only 300C. The action of the Moon, overlooked until now, is thought to have compensated for this difference and kept the geodynamo active. Their work is published on 30 march 2016 in the journal Earth and Planetary Science Letters. The full article is here: http://www.moondaily.com/reports/The_Moon_thought_to_play_a_major_role_in_maintaining_Earths_magnetic_field_999.html :mcook: [/quote] [i]Since neither the Earth's rotation around its axis, nor the direction of its axis, nor the Moon's orbit are perfectly regular, their combined effect on motion in the core is unstable and can cause fluctuations in the geodynamo. This process could account for certain heat pulses in the outer core and at its boundary with the Earth's mantle. Over the course of time, this may have led to peaks in deep mantle melting and possibly to major volcanic events at the Earth's surface. [b]This new model shows that the Moon's effect on the Earth goes well beyond merely causing tides.[/b][/i] :s27moon: [/quote]

I accidentally deleted the OP of this thread during some glitch issues on GLP this morning (10/30/17).
I will be posting some useful links in the next post to make it easier for those posting so you don't have to scroll through a massive OP. :)
I had to delete the first two comments on this thread to do so, but wanted to keep them so I've put them below.
5* and I'm on board.. Simple.. I'm sorry about CH.. He will be missed greatly..
but, the continuation of EQ is an important thing because it's connected to so many things..
Thank you!!! Simple... I will be here.....

I also would like to mention that I know this thread has MANY pages and that it can be somewhat intimidating to join/chime in on a long standing thread as a new member/AC (I've experienced it when I first joined GLP), but we are a VERY welcoming group to those who newly join us. We are a small family of sorts who are all mostly interested in the same earth-related topics (quakes/solar/volcanoes/weather/etc.) and share info on each of those topics as well as 'off-topic' discussions. We genuinely care for one another here and even when we do not agree with each other, we ALWAYS respect each other.
I truly enjoy when new folks join us here. All that I ask is to show respect. :)
