How long before our magnetic field disappeared and how long after that would we be dead due to radiation?

mfb said:Do you have a scenario where melting heat gets released (so the material gets hotter) and the whole Earth gets solid at the same time?
DrStupid said:This thread is about a sudden phase transition of the Earth's core. A scenario where the whole Earth gets solid would be another topic.
davenn said:no, its the point of this topic
the magnetic field won't suddenly/permanently collapse unless the core suddenly/permanently stops rotating and that won't happen unless the outer liquid core suddenly/permanently becomes solid
phinds said:No, you have equated the whole Earth turning solid (which is NOT the topic of this thread) to the inner and outer core turning solid (which IS the topic of this thread). I'm assuming of course that you realize that the inner and outer core do not make up the entire earth. I am agreeing w/ DrStupid and I suspect that you actually agree w/ him as well, but had some misunderstanding about his post.
Mr.CROWLER said:... So does anybody know how long we would have our magnetic field after the core becomes completely solid? Would it disappear instantly?
davenn said:No I haven't, the rest of the Earth is already basically solid ... its only the outer core that's liquid.

If the earth's core were to abruptly turn solid, it would have a significant impact on the planet's geology and atmosphere. The solid core would result in a decrease in the earth's magnetic field, which would cause a decrease in protection from solar radiation. This could lead to an increase in harmful UV radiation and disrupt communication and navigation systems that rely on the magnetic field.
If the earth's core were to turn solid, it would have a direct impact on the planet's rotation. The solid inner core is responsible for providing the planet's spin and maintaining its rotation speed. With a solid core, it is possible that the earth's rotation could slow down or even stop, leading to major consequences for the planet's climate and ecosystems.
It is unlikely that a solid core would directly cause earthquakes and volcanic eruptions. However, the sudden change in the earth's internal structure could potentially trigger seismic activity and volcanic eruptions in the short term. Over time, the solid core would also affect the movement of tectonic plates, potentially leading to more frequent and intense earthquakes and volcanic eruptions.
The sudden solidification of the earth's core would have a catastrophic impact on the planet, making it difficult for humans to survive. The decrease in the magnetic field would result in increased exposure to harmful radiation, while the change in the earth's rotation could lead to extreme weather patterns and changes in the planet's climate. Additionally, the disruption in communication and navigation systems could make it challenging to sustain human life on earth.
The earth's core is made up of primarily iron and nickel, which are solid at extremely high temperatures and pressures. However, the core remains in a liquid state due to the intense heat generated by radioactive decay and the earth's own gravitational pressure. The chances of the core suddenly turning solid are incredibly slim, as it would require a significant and sudden change in the earth's internal processes, which is highly unlikely to occur.
