It is believed to be an iron–nickel alloy, and may have a temperature similar to the Sun's surface, about 5778 K (5505 °C). The location of mantle is around the core of earth. The earth is divided in to four layers:CRUST, MANTLE, OUTER CORE and INNER CORE. The outer core is the third layer of the Earth. Convection in the outer core, combined with the Coriolis effect, gives rise to Earth's magnetic field. The outer core, one of the three layers of the Earth, is approximately 1,430 miles (2,300 kilometers) thick and between 7,200 and 9,000 F. According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form. [1][2], Without the outer core, life on Earth would be very different.

Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. Your IP: Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. The Outer Core The Outer Core is the second to last layer of the Earth. The outer core of the Earth is a liquid layer composed of iron and nickel. Tidal dissipation and the strength of the Earth’s internal magnetic field. Those in the "outer inner core" are lined up north to south. Both the outer and inner cores are made almost entirely of nickel and iron. Since it is a liquid, the outer core can spin, and it does.

What are the different plate activities that shape the Earth’s lithosphere? Bruce A. Buffett 2010. Earth's innermost section is called its inner core, and is believed to be just as hot as the sun's surface. The outer core is in the range of 200 to 300 kilometers (125 to 188 miles) thick. However the upper and lower mantles make up a large portion of the earth's layers when compared to the other layers. The outer core of the Earth is a liquid layer about 2,260 kilometers thick. What is the outer core of the Earth called? Why do coal miners keep hoping the mines will reopen? The Moon’s structure is similar to that of the Earth’s with a crust followed by a mantle, an outer core, and a solid iron inner core.

The latter temperature refers to the inner core. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.Oct 1, 2008. The transition between the inner core and outer core is approximately 5,000 km (3,100 mi) beneath the Earth's surface. The first one is information on the inner core. The Earth's core is the part of Earth in the middle of our planet. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances.
