it works like air and a radiator the heated air rises and cools then falls and the process is repeated again and again
High temperatures in Earth's mantle can cause the melting of rock, leading to the formation of magma. This process can result in volcanic activity when magma rises to the surface. Additionally, the high temperatures contribute to the convection currents within the mantle, driving tectonic plate movements and influencing geological processes like earthquakes and mountain building.

Magma
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
Radioactive decay within the deep interior of the Earth causes convection currents in the magma of the mantle. The continental plates float on top of the mantle, and the currents push them. That is why continents drift.

Mantle is part of the Earth's lithosphere.
plate tectonic and magma
The process of continuous heating and cooling of magma in the mantle is known as magma convection. This movement of molten rock helps distribute heat and promote mixing within the mantle, influencing volcanic activity and plate tectonics.
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Magma
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.

If it were molten, it would be called magma.
