When eartquakes erupt only certaing wavelengths can travel through both liquids and solids, so when the scientists measure to see at what point in the earth the waves refract they can then tell what parts are solid and what parts are liquid

What is the order of earths layers from most dense to less dense?
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
What is hotter inner mantle or outer mantle?
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
What is more dense inner-core or outer-core?
The inner core is more dense than the outer core.
Describe what makes up most of Earth's inner core?
The inner core of the Earth is composed mainly of a nickel-iron alloy. There's a liquid outer core that is made of iron and is very dense. The inner core is made of solid iron and nickel.
What is a sentence using inner core?
inner core is the earths center .
Is Earth's inner core surrounded by a liquid outer core?
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
Why do scientists believethat the inner core is the source of earth's magnetic field?
The core is a dense chunck of metal that influence the earths magnetic field.
What happens in earths interior to produce earths magnetic?
The movements in the liquid inner core.
What is the hot liquid that surround the earths inner core?
magma
Is the solid outer core more dense than the liquid inner core?
This question is based on a false assumption that the outer core is solid and the inner core is liquid. This is incorrect. It is in fact the inner core that is solid (and so is the most dense) and the outer core which is liquid.
What happens in earths interior produce earths magnetic field?
The movements in the liquid inner core.
Why the inner core doesn't move like liquid?
Its too dense.
What are the parts of the earths core?
The solid inner and liquid outer core.
What is the order of earths layers from less dense to most dense?
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
What is Difference between earths inner core and outer core?
The inner core Is solid and the outer core in liquid
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
How does earths inner core affect seismic waves?
They go faster through the inner core than the liquid outer core
