WebThe mantle is like this. When it is under stress for long periods of time, it can flow. Due to the incredibly high temperatures and pressures near the center of the Earth, the outer core is liquid iron and nickel, while the inner core is solid. The motion of the liquid outer core is what gives Earth its magnetic field. WebIt is the movement of the fluid iron in the outer core that creates Earth’s magnetic field (see section 4.2 ). The outer core is 2300 km thick, and has a density of 12 g/cm 3. extends from the outer core to just under Earth’s surface. It is 2900 km thick, and contains about 80% of the Earth’s volume.
