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).

What layer of the earth is the solid dense center of earth?
That is the core of the earth.
Earth inner core definition?
solid center of earth
If the center of the earth is the hottest why is it solid?
because that is where rocks come from,and rocks are solid
What evidence is there that the Earth is solid and made of layers?
You can stand on it which proves its solid, there are volcano's which prove its not solid in the center
The solid layer at the Earth's center is known as the?
This is the inner core.
If the center of the earth is its hottest part why is it solid?
What is a solid center of eath
What layer of the earth is the solid dense center of earth?
That is the core of the earth.
Earth inner core definition?
solid center of earth
What solid metal in the center of the earth?
The core
Is the center portion of earth in liquid or solid form?
The center of the earth, known as the "inner core" is a solid sphere that consists of an iron-nickel alloy.
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.

Is the center of the earth a solid?
no it's molten metals

You can stand on it which proves its solid, there are volcano's which prove its not solid in the center
What is the solid material at Earth's center?
It is an iron and nickel alloy.
What is at the center of earth?
A solid metal ball of nickel and iron
What solid iron and nickel at the Earth's center?
the answer is the outer core
