The Outer Core is composed of iron and some nickel. The inner core has the properties of a solid whereas the outer core prevents the passage of S waves suggesting that it is a liquid.
The inner core is thought to be 2440 km across and when you include the liquid outer core of the Earth the entire core measures 6800 km across.
Facts about the outer core. The outer core is made of a mixture of iron and nickel with smaller amounts of silicon and oxygen. The outer core is the middle layer of the Earths three layers and is located about 1800 miles below the Earths crust the top-most surface of the Earth. The parts near the core reach 4000 F 2204 C.
Today the boundary between the mantle and the outer core is known as the Gutenberg discontinuity. Facts about Outer Core The outer core of the Earth is a liquid layer about 2260 km thick composed of iron and nickel which lies above the Earths solid inner core and below its mantle. It is made of iron and nickel.
We call the outside part of a loaf of bread the crust. As Earth spins on its axis the iron inside the liquid outer core moves around. About twice as big as the Moon.

The Earths outer core was discovered by Beno Gutenberg in 1913. The mantle is solid but the high heat causes the mantle to move slowly beneath the Earths crust.
There are two different types of crust. Its outer boundary lies 2890 km 1800 mi beneath Earths surface. He was studying seismic waves traveling through the earth using seismographs stationed around the planet.
This is above the Earths solid inner core and below the mantle. The crust is made up many types of rocks which are lighter than the rocks that make up the mantle. Its outer boundary lies approximately 2890 km 1800 mi beneath the Earths surface.
The outer core is the third layer of the Earth. The strong magnetic field is caused by convection in the liquid outer core. This spinning causes the entire planet to be.
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. The area lies about 2890 km 1800 mi beneath our feet. Scientists know that the outer core is liquid and the inner core is solid because.
The outer core is responsible for Earths magnetic field. The transition between the inner core and outer core is located approximately 5150 km 3200 mi beneath the Earths surface. Outer core The outer core of the Earth is a liquid layer about 2260 kilometers thick.
The Outer Core is thought to be as hot as 6100 degrees celsius 11000 Ferenhaiet It has been determined that this layer is liquid based on the extensive study of seismic waves and the way in which they bounce off the center of the Earth. The outer core is the outer layer of the core that is made of liquid iron and nickel. Together the crust and the upper mantle form the Earths outer shell.
The parts closest to the Earths surface reach about 1600 F 871 C. The continental crust makes up the land on Earth. The earths inner core is a solid ball of iron nickel and other metals while the outer core is liquid metal composed of iron and nickel as well.
Earths outer core is a fluid layer about 2400 km 1500 mi thick and composed of mostly iron and nickel that lies above Earths solid inner core and below its mantle. The outer core consists of hot lava that is comprised mostly of iron and nickel. This layer is so hot that all metals in it are in a liquid state.
The outer core officially begins at a depth of 2550 km below the earths surface down to a final. The temperature of the inner core is estimated to be about 5400 degrees C or 9800 degrees F far beyond irons melting point. The outer core is the first layer of the core and it extends to a depth of approximately 2890 kilometers below the Earths crust and measures 2300 kilometers thick.
The inner core is the hottest region and the innermost region of the Earth. There is very few rocks and iron and nickel ore left in the Outer Core because of the Inner Core melting all the metal into liquid magma. S-waves do not go through the outer core.
Since it is a liquid the outer core can spin and it does. We use the same word to describe the outer layer of. Convection currents in the outer core are due to heat from the even hotter inner core.
