The correct answer is the "core." The Earth's core is found at the center of the Earth, and it is divided into two parts: the inner core and the outer core. The inner core is solid, primarily made of iron and nickel, and it has extremely high temperatures and pressures. The outer core is a liquid layer surrounding the inner core and is also composed mainly of iron and nickel. It is because of the movement of the molten outer core that Earth has a magnetic field. To find the answer to this question, you can refer to any reputable source that provides information about the layers of the Earth, such as geology textbooks, websites dedicated to Earth sciences, or educational videos on the topic.
