Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. [1][2][3] The outer core begins approximately 2,889 km (1,795 mi) beneath Earth's surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath Earth's surface at the in...

Jun 11, 2024 · Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s core is the very hot, very dense center of our planet.

Mar 7, 2023 · The outer core is the second innermost layer of the Earth, situated between the inner core and the mantle. It is largely composed of iron and nickel, which are in liquid form because of the lower pressure than that found in the inner core.

The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core. The temperature of the outer core ranges from 4400 °C in the outer regions to 6100 °C near the inner core.

Aug 1, 2023 · The Outer Core. The outer core extends from 2,900 km to about 5,150 km beneath the Earth’s surface. It mainly consists of liquid iron and nickel. The motion within this layer generates the Earth’s magnetic field. The Inner Core. The inner core is …

Oct 11, 2023 · Earth’s outer core is a layer of mostly molten metal that lies between the solid inner core and the mantle. This outer core primarily comprises liquid iron and nickel, with some other trace...

Mar 9, 2009 · Deep within the Earth, thousands of kilometers below your feet is the core of the Earth. Once thought to be a single ball of iron, scientists now know that the Earth’s core contains a solid inner...

The structure consists of an outer silicate solid crust, a highly viscous asthenosphere, and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core.

Mar 30, 2024 · The outer core is situated approximately 2,900 kilometers (1,802 miles) beneath the Earth’s surface, resting between the solid mantle above and the solid inner core below. This depth places it beyond our direct reach, making its study incredibly challenging.

Nov 21, 2023 · The outer core of the earth is a liquid mix of elements, mostly iron and nickel, with smaller amounts of silicon and oxygen. It goes from a depth of 2550 km below the surface of the earth to 4750...
