How does the center of the earth stay molten
WebMar 1, 2024 · The inner core of planet Earth was once molten. But it solidified within the past 565 million years, a new study suggests. That would have been just in time to save the planet’s protective magnetic field from imminent collapse. It also would have kick-started that field into its current, powerful phase, the study says. WebThe earth formed in the molten state. The liquid iron which is very dense fell to the center. The rest of the earth is made up of silicate materials with SiO2 being the main component. The Earth's mantle is made up of low silica compositions (around 40% silica) and that is _denser_ than the high silica stuff that makes up the continental crust.
