What is the deepest layer of the planet?

The deepest layer of the Earth is the inner core, which is primarily composed of iron and nickel. It is located about 3,200 kilometers (approximately 2,000 miles) beneath the Earth's surface and is solid due to the immense pressure despite its high temperature, which can reach up to 5,700 degrees Celsius (about 10,300 degrees Fahrenheit). Surrounding the inner core is the outer core, which is liquid and responsible for generating the Earth's magnetic field.
