In the Earth's mantle, you would find a solid layer composed mostly of silicate minerals rich in iron and magnesium. The mantle is characterized by high temperatures and pressures, leading to the gradual flow of its materials over geological time scales. It contains partially molten rock, known as magma, and is responsible for driving tectonic plate movements. Additionally, you might encounter various mineral formations and convection currents that contribute to the dynamics of the Earth’s interior.
Thermosphere or the ionosphere is the thickest layer on earth. It reaches a height 400 kilometers.
It isn't. At least not by Earth scientists! There is no reason based on the evidence to believe that there are significant void spaces (i.e. caverns) within the mantle (despite what you might see in films such as "The Core").
No we would over heat and die!
Most of the mass of the Earth is in the mantle, most of the rest in the core; the part we inhabit is a tiny fraction of the whole
The Earth's crust lies above the mantle.
If the convection currents in the earth's mantle slowed down then the mantle would slow down. Eventually, the mantle would stop all movement.

It is in the mantle, consisting of the upper and lower mantle, which measures about 2855 km. It is situated below the Earth's crust, about 35km from Earth's surface.
The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.
In some places, Earth`s crust thins enough to see mantle.
Nickel
If the mantle of the earth interior were to cool down the convection currents and plate tectonics would stop. That would mean that there would be no more earthquakes or volcanoes.
After about 20 miles, you would reach the mantle.
That would be the skin, if you were comparing that apple to the Earth.

The avocado's flesh would best represent the Earth's mantle in this analogy. Just like the mantle is the thickest layer beneath Earth's crust, the flesh is the thickest part of the avocado surrounding the pit. Both the mantle and avocado flesh occupy a substantial portion of their respective structures.
