Wat is the fluid layer in the earth called?

im in a science lesson and need the answer


thankyouWat is the fluid layer in the earth called?
There is a common misconception amongst the general public with regards the structure of the earth. Put in the simplest form the Earth has 4 distinct zones, excluding the atmosphere or hydrosphere. The crust is the uppermost of these, consisting entirely of solid rock (excluding intrusions such as batholiths). The next layer is the mantle,which is also solid, but said to be plastic (because it can move; but definately is solid). Only localised melting occurs in the mantle. The liquid layer is the outer core (and we know this because the Secondary component of Seismic waves which cannot pass through liquid, stops at the Gutenberg Discountinuity (Core-Mantle boundary.) The inner core is a solid mass of mostly Iron with smaller amounts of nickel and traces of other elements.


Hope this helps, but the mantle is definately solid and the outer core definately liquid (or believed to be by Geologists worldwide)Wat is the fluid layer in the earth called?
The only region of the earth that is believed to be liquid is the outer core. Because of the high temperatures and pressures the mantle can be considered solid although can be deformed under pressure.





Magma on the other hand is formed at relativly shallow depth that are characterised by high temperature and low pressure - within the upper mantle. In no way does the liquid outer core have any relationship with the magma that is ejected as lava.
If it is referred to water then hydrosphere and if it is referred to earth's structure then its core comprising of magma that comes out in the form of lava during volcanic eruptions.
The Core (inner) is liquid. The liquid is called magma. when the molten magma comes out of a volcano it's then called 'lava'.





Why the thumb-down?.. it's correct.
The word you are looking for is MAGMA The Oxford Dictionary says it is fluid or semi-fluid beneath the earths surface from which lava or other ingenous rock is formed by cooling.
