no it's molten metals
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.
The core
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.
The Earth's core is mostly liquid, with a small solid inner core at the very center.
It is called the inner core.
It is an iron and nickel alloy.
A solid metal ball of nickel and iron
the answer is the outer core
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.
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.
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.
The center of the Earth is hot due to the immense pressure from overlying rock layers, not because of sunlight or other external heat sources. The pressure keeps the inner core solid despite the high temperatures.
