I just wanna ask question... If we put flamed coal in a can to stop the flaming coal because as we all know fire needs oxygen to continue burning..
this is the question... there are 3 layers of the earth.. the crust is thick and it covers the mantle and the core.. why is it that there is constant magma in mantle and the core if there is no oxygen present in the lower layers of the earth? the earth blankets the other layers right.?it prevents the oxygen to enter the lower layers.. why is it there is a constant burning magma underneath
