magma
The core of the earth contains radioactive material and this causes a convection current in the mantle.
No, shale rock is not a melted material inside the earth. It is a type of sedimentary rock formed from compacted mud and clay particles. Melted materials inside the earth form igneous rocks through volcanic or intrusive processes.
The term for the circular movement of material inside Earth's mantle is convection. Heat from Earth's core causes hot material to rise, while cooler material sinks, creating a continuous, circular flow that drives plate tectonics.

Magma is inside the volcano, and it becomes lava when it comes out. :)
Intrusive igneous rocks.
magma
Seismic waves traveling through the Earth have indicated a decrease in material density in the mantle transition zone. Another indicator is the presence of magma chambers near the Earth's surface, suggesting a decrease in density as material rises from the mantle. Additionally, the behavior of gravity anomalies can also suggest a decrease in material density inside the Earth.
