The centre of the Earth (the inner core) is actually composed of iron and nickel rather than rock. It is solid because the very high pressure drives up the melting temperature of these metals beyond the temperature at the core.

Why doesnt the rock in the center of the earth liquefy?

The rock in the center of the Earth doesn't liquefy because of the immense pressure from the layers of rock and metal above it. This pressure prevents the rock from melting despite the high temperatures in the Earth's core.


Why doesn't the rock in the center of the earth liquefy?

The center of Earth is not rock but metal. While that metal is well above its normal melting point it is kept solid by the enormous pressure found inside Earth.

What Circle on Earth's surface has the center of Earth as its center?

Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.


Why doesn't the rock of the center of the earth liquefy when it is at such a high temperature?

The rock at the center of the Earth is under immense pressure, which increases with depth due to the weight of the overlying material. This high pressure raises the melting point of the rock, preventing it from liquefying despite the extreme temperatures that can reach around 5,000 to 7,000 degrees Celsius. Additionally, the composition of the material, primarily iron and nickel, contributes to its solid state under these conditions. Hence, the combination of high pressure and specific material properties keeps the Earth's core solid.
