Magma is molten rock and while it may rise to the crust and come out in volcanoes, it DOES NOT sink to the core.
Do not think that the deep earth is made of molten rock, it is NOT, the Earth's mantle is solid.
This said, even stuff which is solid flows like a liquid very slowly over Geologic time and the rocks of the mantle do indeed convect. as this happens the Earths continental, surface plates are moved around the planet.
Magma
The Mantle. It is the largest and thickest layer in the earth. But this answer might not be actually true. Because the earth has all these layers and the mass is added up. -By Olivia Agbo A 12 year old. Thank you for your support.
Magma seeps up through the two plates from the mantle and form volcanos.
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
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.
Mantle is part of the Earth's lithosphere.

If it were molten, it would be called magma.

That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
Once magma breaks through the earths crust it is called"lava"
in the mantle above the slab
Plates on the Earth's mantle are carried around by convection currents from the magma. This happens incredibly slowly.
