hot burning rock and magma
The centre of the Earth's core - is a solid iron sphere.
The Wikipedia article on "Earth" mentions that at the center, the temperature "may" be up to 6000 degrees Celsius.

I know it is nickel
The primary source of heat energy driving plate tectonics on Earth is radioactive decay in the planet's interior. This process generates heat through the decay of radioactive elements within the Earth's core and mantle, resulting in convection currents that drive the movement of the planetary plates.
The two types of Earth's crust are continental crust and oceanic crust. Continental crust is thicker, less dense, and composed mainly of granite, while oceanic crust is thinner, denser, and made up mostly of basalt.
The radius of Earth's inner core is roughly 1,220km (658miles), made of mostly (about 80%) solid iorn.
Because the outercore applies pressure to the innercore. Its like the book stack effect, pile up 5 books. Which book has the most pressure on it? The bottom. Now imagine that being a CIRCLE of books, the INNERbook or the innercore would have the most pressure.

The Earth's crust is made up of several major plates, including the North American Plate, Eurasian Plate, and Pacific Plate, among others. These plates are constantly moving and interacting with each other, resulting in various geological processes such as earthquakes and volcanic activity.
