The discussion revolves around the potential effects on Earth's rotation speed if the molten core were to solidify. It explores the implications of volume changes in the core and considers the relationship between core state and Earth's magnetic field, as well as the influence of tidal interactions with the Moon.
Participants express differing views on the effects of core solidification on Earth's rotation speed, with some supporting the idea of increased speed while others emphasize the significance of tidal interactions. The discussion remains unresolved.
There are limitations regarding the assumptions about the relationship between core state and rotation speed, as well as the lack of detailed information on the composition and behavior of the Earth's core.
Can you please post some links with references about your question? How much of Earth's core is molten? What is it made up of? Why would it shrink when solidifying? And so on. Thanks for filling our your question further.Prishon said:The question is simple. The molten stuff inside the Earth will get a smaller volume when it solidifies. Will the Earth increase its rotation speed in reaction to this? What about the magnetic field?
