Why is the core of the earth solid and not liquid?
The outer core of the Earth is liquid but traveling deeper the pressure overcomes the extreme heat. Near the center of the Earth, increased pressures are sufficient to inhibit melting so nickel-iron crystallizes and the inner core solidified.Click to see full answer.

The outer core of the Earth is liquid but traveling deeper the pressure overcomes the extreme heat. Near the center of the Earth, increased pressures are sufficient to inhibit melting so nickel-iron crystallizes and the inner core solidified.Click to see full answer. Subsequently, one may also ask, why is the inner core of the Earth solid and not liquid?The inner core is solid because it is made of very dense, or heavy, materials – like iron and nickel. 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.Also, is Earth’s core solid or liquid? The Earth’s core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core. Consequently, why the Earth core is solid? The Earth’s inner core is thought to be slowly growing as the liquid outer core at the boundary with the inner core cools and solidifies due to the gradual cooling of the Earth’s interior (about 100 degrees Celsius per billion years).Why is the outer core liquid?The average magnetic field strength in the Earth’s outer core was estimated to be 2.5 millitesla, 50 times stronger than the magnetic field at the surface. The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to the inner core.
