We base our theory of their state (solid or liquid) on seismic wave recordings. We base our ideas of its composition on meteors which have landed on earth.
High temperature and high pressure are inferred to occur within Earth's stiffer mantle. As depth increases in the mantle, both temperature and pressure increase. This combination of high temperature and pressure allows for the solid rock to exhibit ductile behavior, resulting in the flow of solid material over long periods of time.
Scientists divide Earth's interior into the crust, mantle, and core based on their composition and physical properties. The crust is the outermost layer and is made of solid rock, the mantle is predominantly solid but can flow slowly over geological timescales, and the core is mostly metallic and divided into a liquid outer core and a solid inner core based on their differing states of matter.
crust
The layer of solid unbroken rocks in the Earth's crust is called the lithosphere.
Lithospheric plates.

No. It is a solid.
no it is not true. there is solid iron and nickel in the Earths core
no
The crust.
Lithosphere is solid part of earth .
Take a walk outside. Then you will be walking on the Earth's solid surface.
a solid ball of iron
solid and liquid
It is said that the crust and the inner core are to be solid.
It is solid but there is a method of analysis to test.
