Detailed explanation-1: -Magma originates in the lower part of Earth’s crust and in the upper portion of the mantle. Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle.
Detailed explanation-2: -Earth Science FAQs-Volcanoes The Earth’s mantle, on which the crust is lying on, is not made of liquid magma. It is not even made of magma. The Earth’s mantle is mostly made of solid rock.
Detailed explanation-3: -The crust, mantle and inner core of the earth are all solid rock (or iron in the case of the core). The only large portion of the earth’s interior that is liquid is the outer core, and lava does not come from there (again, if it did, it would be molten iron).
