How is magma/lava created? i don't know alot of physics that is why?

Question

i don't ask there. it takes a long time to look up all their definitions and try to partially understand what they mean. especially when they use principal of superposition, F=GMm/R squared, HC=71Km/s/megaparsec AND expanding,

if i knew and understood all those things, and all of physics, i probably would be too busy inventing things to be here and probably wouldn't be asking for your opinion greed.

Answer 1

Well, I don't think we will be using parsecs or superposition for this.

Lava is melted rock.  The heat of the earth melts rock and it is ejected through open pathways from below the crust to the surface.  

Look up volcanoes.
