(I) Seismic shear waves (S-waves) are unable to travel through liquid media and for the outer core it has been observed that S-waves are not transmitted.
(II) Scientists are able to determine the angular momentum of the Earth and came to the conclusion that there numbers wouldn't add up if all of Earth was solid (its like spinning a raw and a boiled egg).
(III) Numerical modelling relies on a liquid outer core to generate Earth's magnetic field.
(IV) Our knowledge of pressure and temperature conditions in the deep Earth predicts that iron-nickel alloy in the depth of the outer core exists in liquid form.
The Earth's core is not made up of rocks. It is made up primarily of nickel and iron.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
The liquid layer of the Earth's core is called the outer core.
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
earths magnetic field is generated by the circulation of liquid metal.
the mantle
the outer core is liquid; the inner core is solid
in the earts oute is the mantle :) thank you :) ml ri
The outer core is a liquid that is in between the inner core and mantle. It is 2,000km thick.
hot liquid
liquid iron
No. It is a solid.
The movements in the liquid inner core.
no
hydrosphere
most of the water is in the cytoplasm
The movements in the liquid inner core.
