The centre of the Earth is widely accepted to be solid because seismic waves were noted to be deflected from a boundary deep within what was believed to be a liquid core. This was first noted in 1936 by the Danish seismologiest Inge Lehmann.
One theory as to the reasoning for this is stated by Princeton geosciences professor Jeroen Tromp in the following quote:
"The inner core is basically the result of the slow cooling of the outer core. The temperature drops below the melting point at the inner core boundary so over time, slowly, the inner core has crystallized within the liquid outer core. That will continue and eventually there won't be a liquid outer core anymore. It will be gone."
However, he has a ridiculous name, and is probably wrong, and the more widely accepted theory is that the high pressure (approximately 330 GPa) raises the melting point of the iron at the Earth's core to between 5730 and 6730 Kelvin (5456.85 - 6456.85 C / 9854.33 - 11654.33 F), with the Earth's core estimated to be around 5,700 K (5430 C / 9,800 F).

Yes, the center of the Earth is believed to be a solid iron core surrounded by a liquid outer core and solid mantle and crust.
Is Earth's core solid or liquid?
The Earth's core is mostly liquid, with a small solid inner core at the very center.
What is the solid area close to the center of the earth called?
The solid area close to the center of the Earth is called the inner core. It is a solid ball of mostly iron and nickel that is believed to be at extremely high temperatures and pressures.
What is at the center of the Earth?
At the center of the Earth is a solid inner core made mostly of iron and nickel, surrounded by a liquid outer core.
The solid center of the earth is called?
The solid center of the Earth is called the inner core. It is composed mainly of iron and nickel and is estimated to be about 1,200 kilometers in radius.
Is the center of the earth solid?
Yes, the center of the Earth is believed to be a solid iron core surrounded by a liquid outer core and solid mantle and crust.
What solid metal in the center of the earth?
The core
Is center of gravity lies where there is no mass?
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.

It is an iron and nickel alloy.
What solid iron and nickel at the Earth's center?
the answer is the outer core
What is a layer of solid metal at the very center of Earth?
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.
Is the center portion of earth in liquid or solid form?
The center portion of Earth is believed to be in a solid state, primarily made up of a solid iron nickel alloy due to the high pressure and temperature. Surrounding this solid inner core is a liquid outer core composed mainly of iron and nickel.
What is the solid area close to the center of the earth called?
The solid area close to the center of the Earth is called the inner core. It is a solid ball of mostly iron and nickel that is believed to be at extremely high temperatures and pressures.
