What is the center of the Earth referred to as?

The center of the Earth is referred to as the core, which is composed primarily of iron and nickel. The core is divided into two parts: the solid inner core and the liquid outer core. This region is extremely hot, with temperatures that can reach up to about 5,700 degrees Celsius. The core plays a crucial role in generating the Earth's magnetic field through the movement of molten metal in the outer core. It is located beneath the mantle and is different from the crust, which is the outermost layer of the Earth, and the asthenosphere and upper mantle, which are layers above the core. Understanding the structure and composition of the Earth's layers, particularly the core, is fundamental in geology and physics, as it helps explain phenomena such as seismic activity and the behavior of magnetic fields.
