How much magma is there in the Earth?

    There really is no exact measure of how much magma there is inside the earth. It is estimated that about 10-20% of the mantel is magma, and the outer part of the Earth’s core is liquid iron, another form of magma. The inner core is completely solid due to the extremely high amounts of pressure. So in total, maybe 20-25% of the earth is magma, but no one has an exact estimate.
