What Is the Outer Core? The outer core is part of the core, which is one of the three major layers of the Earth. The core is the deepest and hottest layer and is mostly composed of metals, and it is beneath the Earth's mantle. The outer core is the first layer of the core, and it extends to a depth of approximately 2,890 kilometers below the Earth's crust and measures 2,300 kilometers thick.

is ﻿ ﻿ Inner The fourth and final layer of the geosphere is the inner core. The inner core (1,220 km thick) and the outer core combined is about 15 percent of the Earth’s volume. The inner core is mostly comprised of iron. The inner core’s temperature can reach up to 6,000℃.

Inner core The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius.[1][2] It is composed of an iron–nickel alloy and some light elements. The temperature at the inner core's surface is approximately 5,700 K (5,430 °C), which is about the temperature at the surface of the Sun.

What is the inner core made of? Best Answer: Solid nickle & iron. Even though the outer core is liquid, the inner core is solid b/c it is compressed by immense pressure. Source(s): http://en.wikipedia.org/wiki/Inner_core.

The Earths Interior A look At The Layers of The Inner Earth There is an outer core that is liquid and an inner core that is solid. 1  Outer core Is about 2100 km thick. It makes up about 30 % of the Earth's total mass.  Inner coreIs about 1300 km thick. It makes up about 2 % of the Earth's total mass.

What is the Earth's core made up of? The outer core is made up of liquid iron and nickel, along with lighter elements such as sulfur and oxygen. The inner core is made up of solid nickel and iron, and contains heavy and radioactive elements as well. There are two parts to the Earth's core: the inner and outer core. The inner core is made primarily of iron and is a solid, despite existing at a temperature range of approximately 5000-7000K (5273-7273 degrees Celsius). A solid state is maintained due to incredible pressure (iron normally melts at around 1420K (1147 degrees Celsius)).

Earth's Rotating Inner Core Shifts Its Speed Under the liquid-metal outer layer of the Earth's core is a solid ball of superhot iron and nickel alloy about 760 miles (1,220 kilometers) in diameter. Scientists recently discovered the inner core is, at 10,800 degrees Fahrenheit (6,000 degrees Celsius), as hot as the surface of the sun.

- The Lower Mantle- part of the second layer of the earth which is mostly melted rock. The whole mantle going down is 1800 miles down. The Outer Core- is made up of liquid metals mostly iron nickel and minor sulfur. The outer core goes 1375 miles down. The Inner Core- the most inner layer of the earth which is solid and made of iron and nickel. The inner core is 1750 miles to the center. How the layers of the Earth were created.

Earth's Internal Layers: Crust, Mantle & Core Let's start from the inside and work our way out. Earth has a core, but this is really two distinct parts: the inner core and the outer core. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.

Crust, Mantle, Outer Core, and Inner Core - The mantle's state of matter is Solid. -The composition of Earth's mantle is molten/solid rock (magma). - The Outer Core is the second to last layer of the Earth. It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field.

What Is Earthâs Core Made of? The outer core is about 1,400 miles thick, and it's made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form. In the outer core, they're in a very hot liquid form.

Outer core Outer core. The outer core of the Earth is a liquid layer about 2,300 km (1,400 mi) thick and composed of iron and nickel that lies above Earth's solid inner core and below its mantle.Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.ecause of its high temperature, modeling work has shown that the outer core is a low viscosity fluid (about ten times the viscosity of liquid metals at the surface) that convects turbulently. Eddy currents in the nickel iron fluid of the outer core are believed to influence the Earth's magnetic field.

What Evidence Led Scientists to Conclude That Earth's Outer Core Is Liquid? The outer and inner core are both composed mainly of iron. By measuring information from seismic waves, scientists can conclude that the iron in the outer core and inner core exist at different densities, so exist as different states of matter: liquid and solid.

Earth's Rotating Inner Core Shifts Its Speed Under the liquid-metal outer layer of the Earth's core is a solid ball of superhot iron and nickel alloy about 760 miles (1,220 kilometers) in diameter. Scientists recently discovered the inner core is, at 10,800 degrees Fahrenheit (6,000 degrees Celsius), as hot as the surface of the sun. Churning in the liquid outer core results in the dynamo that generates Earth's magnetic field.

What Happens to the Temperature & Pressure as You Get Closer to the Earth's Core? Temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above. The outer core consists mainly of liquid iron, along with substantial amounts of nickel and sulfur. The Earth's magnetic field is generated by the outer core.

- The outer core of the Earth is a fluid layer about 2,300 km thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km beneath the Earth's surface. Unlike the inner core, the outer core is liquid. The inner core is also referred to as the solid core.
