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?
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.

The molten core of the Earth is the innermost layer of the planet, composed primarily of iron and nickel. It is important because it generates the Earth's magnetic field, which protects us from harmful solar radiation and helps guide animals during migration.
The molten core plays a crucial role in the Earth's rotation. As the liquid iron in the core moves, it creates a magnetic field that interacts with the Earth's solid outer layers, causing the planet to rotate.
There is a common misconception that the rotation of the Earth is directly linked to the state of its core. However, the Earth's rotation is primarily determined by its angular momentum, which is not affected by changes in the core's state. Therefore, the rotation speed of the Earth would not be significantly impacted if the molten core solidified.
Scientists believe that the Earth's core has been solidifying at a very slow rate since the planet's formation. However, the core is still primarily liquid and is not expected to solidify completely for billions of years.
If the Earth's core were to solidify completely, it would likely have some impact on the planet's magnetic field and potentially affect the Earth's climate. However, this process would occur over a very long period of time and is not expected to have any immediate or drastic effects on our planet.
