Apr 25, 2014 · Obviously because the inner core is solid but the outer core is liquid, we must conclude that the drop in temperature vs the drop in pressure must be lower than the gradient of 16 degrees/GPa shown in the diagram below (link to source), given that at the outer-core temperature has exceeded the melting point of iron/nickel, which is a function of pressure.

outer core–inner core boundary. Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon 's radius. [1][2] There are no samples of the core accessible for direct measurement, as there are for Earth's ...
Sep 28, 2011 · The inner core of the Earth is a huge mass of solid oxygen and the outer core is liquid oxygen. Liquid oxygen and solid oxygen are highly paramagnetic. Think open-minded, change wrong paradigm ...
Apr 25, 2014 · 31. +50. Earth's inner core is solid even though the temperature is so high because the pressure is also very high. According to the Wikipedia article on the Earth's inner core, the temperature at the center is 5, 700 K 5, 700 K and the pressure is estimated to be 330 330 to 360 GPa 360 GPa (∼ 3 ⋅106 atm ∼ 3 ⋅ 10 6 atm).
Jun 11, 2024 · Mars, for instance, has a totally solid core and a weak magnetic field. Venus has a liquid core, but rotates too slowly to churn significant convection currents. It, too, has a weak magnetic field. Jupiter, on the other hand, has a liquid core that is constantly swirling due to the planet’s rapid rotation. Earth is the “Goldilocks” geodynamo.
Flexi Says: Earth's inner core is solid despite even higher temperatures than the liquid outer core. Pressure is also greater in the inner core than in the outer core due to a greater amount of material pressing down. Even though the inner and outer cores are mostly iron, the differences in temperature and pressure conditions cause iron to ...

Scientists know that the outer core is liquid and the inner core is solid because: S-waves stop at the inner core. The strong magnetic field is caused by convection in the liquid outer core. Convection currents in the outer core are due to heat from the even hotter inner core. The heat that keeps the outer core from solidifying is produced by ...
