This molten material is called magma when it is in the ground and lava when it is on the surface. This chapter will describe the classification of igneous rocks, the unique processes that form magmas,...This molten material is called magma when it is in the ground and lava when it is on the surface. This chapter will describe the classification of igneous rocks, the unique processes that form magmas, types of volcanoes and volcanic processes, volcanic hazards, and igneous landforms. Depending on the properties of the lava that is erupted, the volcanism can be drastically different, from smooth and gentle to dangerous and explosive.
