The inner core of the Earth is a solid, dense, and extremely hot metallic sphere located at the center of the planet. It is composed primarily of iron and nickel, with temperatures reaching up to 5,700 degrees Celsius (10,300 degrees Fahrenheit). The inner core is believed to be solid due to the immense pressure at its center, despite the high temperatures. It plays a crucial role in the generation of the Earth's magnetic field and is surrounded by the liquid outer core.
