A super hot ball of: Iron, Nickel and roughly 20% Rock.
The dense center of the Earth is known as the core, and it is divided into two parts: the inner core and the outer core. The inner core is mainly composed of solid iron and nickel, while the outer core is a liquid layer made up of molten iron and nickel.
At the center of the Earth is a solid inner core made mostly of iron and nickel, surrounded by a liquid outer core.
Inner core, which is also the innermost region of the Earth.
The inner core of the Earth is composed mainly of solid iron. It is the innermost layer of the Earth, located beneath the outer core. The immense pressure at the center of the Earth causes the iron in the inner core to be solid despite its high temperature.
The layer that surrounds the center of the Earth is called the core. It is divided into the inner core and outer core, with the inner core being solid and made mostly of iron and nickel, while the outer core is a liquid layer also composed of iron and nickel.
inner core
It is composed of an iron and nickel alloy, and is called the inner core.
At the center of the Earth lies a solid inner core made mostly of iron and nickel, surrounded by a liquid outer core.
The center of the Earth is known as the core. It consists of the inner core, made of solid iron and nickel, and the outer core, made of liquid iron and nickel. The Earth's core plays a crucial role in generating the planet's magnetic field.
The main ingredient of the Earth's inner core is iron. It is believed to be in a solid state due to the immense pressure at the center of the Earth.
The inner core of the Earth is a solid sphere composed mainly of iron and nickel. It is approximately 1,200 kilometers (750 miles) thick and is located at the center of the Earth, beneath the outer core. The inner core is extremely hot, reaching temperatures of up to 5,700 degrees Celsius (10,300 degrees Fahrenheit).
Earth's inner core is believed to be solid iron.
