The upper core, often referred to as the outer core, is composed primarily of liquid iron and nickel and lies beneath the Earth's mantle. It extends from about 2,900 kilometers (1,800 miles) to 5,150 kilometers (3,200 miles) below the Earth's surface. The movement of the liquid metal in the upper core generates the Earth's magnetic field through the dynamo effect. Unlike the solid inner core, the outer core's fluid nature contributes to its dynamic processes and influences tectonic activity.
