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.

∙ 12y agoThis is due to a process called convection where hot fluid rises and cool fluid sinks in a circular cycle motion. The same occurs in many other situations, such as in lava lamps, boiling pasta/rice/etc., and when the upper level of your home is warmer than the lower level.

What are windows to earths interior?
Mantle-derived xenoliths. The magma is mantle and/or subducted-crust-derived. Xenoliths come from the country rock through which the magma rises, so really it's the magma (solidifying as igneous rock) that's the window. For greater depths, seismic analysis is the window.
What layers makes up most earths mass?
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.
When solid rock in the earths mantle melts it forms a liquid rock known as?
Magma
What happens when two tectonic plates move apart?
Magma seeps up through the two plates from the mantle and form volcanos.
Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
magma
What is the rock of earths mantle?
plate tectonic and magma
When rocks return to earths mantle to earths mantle they can eventually melt and become magma. and are the main factors that control this change.?
heat and pressure
is it true magma forms in the deeper regions of earths mantle?
yes
What is the opening on earths surface where magma from the mantle rises and flows out?
Valcano
What is a molten rock from earths mantle?
If it were molten, it would be called magma.

Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
Magma that breack through the earths curst is called?
Once magma breaks through the earths crust it is called"lava"
Where does magma form before it moves toward the earths surface?
in the mantle above the slab
When solid rock in the earths mantle melts it forms a liquid rock known as?
Magma
