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).

Even though it is very hot, these materials don't "melt" very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher. So, even though it is hotter in the inner core, the pressure in the core is also higher, and you can have solid iron-nickel instead of liquid.
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 ...
Feb 17, 2017 · Geologists estimate that the Earth’s core is a sweltering 5,700 K – and yet the inner core is a solid ball of iron. Why it doesn’t liquify is a bit of a mystery, but now a study puts forward ...

Feb 13, 2017 · Belonoshko says that in the extreme heat of the core, atoms no longer belong to planes because of the high amplitude of atomic motion. "The sliding of these planes is a bit like shuffling a deck ...

Feb 14, 2017 · Scientists have a new explanation for why Earth's inner core remains solid - despite being hotter than the surface of the Sun. Turns out, it could be all down to the atomic architecture of the crystallised iron ball at Earth's centre. Researchers suggest that this iron core exists in a never-before-seen atomic state that allows it to withstand ...

Jun 11, 2024 · Inner Core. The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmospheres (atm). The temperature of the inner core is far above the melting point of iron.
