Want this question answered?
There is no layer of Earth that is predominantly molten rock. The only layer of Earth that is liquid is the outer core, however this is mainly iron and nickel. The mantle, the thickest layer of the Earth, contains rock that is "ductile" (i.e. very viscous and able to flow very slowly), but not technically "liquid."
In the mantle
The rock layer beneath the Earth's surface that slowly flows is the mantle. (Given enough time, all rocks, even the most solid, will flow through molecular motion.)The mantle is a slowly convecting layer of rock which flows in order to transfer heat from the core to the Earth's surface. It is this convection that drives the movements of the continents and can cause volcanic mountains to form.The athenosphere is the highly viscous, mechanically-weak and ductilely-deforming upper mantle of the Earth. It is the zone upon which the great rigid and brittle lithospheric plates of the Earth's crust move about. However, the whole mantle is flowing, albeit very slowly.
The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
While still solid, the asthenosphere is able to flow. The ability of a solid to flow is called plasticity. See "What's the matter?" for an activity to demonstrate plasticity. Since the asthenosphere is more liquid than the rest of the mantle, the broken lithosphere plates are able to "float" on it.
The soft layer of rock in the Earth's mantle is called the asthenoshere. The asthenoshere is a solid but able to flow slowly.
Mantle Is The Below Layer Of The Crust In Earth.
Convection currents are found in the plastic mantle in Earth.
The Mantle of the Earth.
The mantle cause the mantle to flow.

The mantle is the solid layer of earth that can flow because of great heat and pressure
solid atoms can not flow they can only slowly vibrate.
In the mantle
Yes, it is a solid with the uncommon characteristic of plasticity. It is a solid with the ability to flow like a liquid, but the mantle moves slowly. If you could kick it, you would stub your toe.
