Lecture 4 Igneous Rocks - University of Illinois
... The Earth's crust and mantle are composed of solid, not molten, rock. So what is the source of magma that produces igneous activity? Magma is generated in the lower crust and upper mantle (at depths of 50 to 200 km also) by (1) raising the temperature, (2) reducing the pressure, (3) adding water. Th ...
