Scientists infer that earth's outer core is liquid based primarily on what studies?
(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.
What else can I help you with?
What type of rocks make up the earths core?
The Earth's core is not made up of rocks. It is made up primarily of nickel and iron.
What creates the Earths magnetic field?
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.
What is the liquid layer of the earths core called?
The liquid layer of the Earth's core is called the outer core.
Earth's magnetic field results from the spinning of the?
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.
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
Which structural layer of earths interior have scientists concluded is liquid?
the mantle
What have seismic studies discovered about earths core?
the outer core is liquid; the inner core is solid
What is in the earths outer core?
in the earts oute is the mantle :) thank you :) ml ri
Is the earths crust a liquid?
No. It is a solid.
What is the earths center?
liquid iron
What is the earths outer core?
The outer core is a liquid that is in between the inner core and mantle. It is 2,000km thick.
Is the earths outer core hot solid or hot liquid or cold solid or cold liquid?
The Earth's outer core is believed to be a hot liquid layer composed primarily of iron and nickel. It is responsible for generating the planet's magnetic field through convective motion of the molten metal.
What happens in earths interior to produce earths magnetic?
The movements in the liquid inner core.
What is the liquid part of the earths called?
hydrosphere
Is the earths outer core a cold liquid?
no
What happens in earths interior produce earths magnetic field?
The movements in the liquid inner core.
What are the two images of the earths layers?
solid and liquid
