WebHow Do Volcanoes Erupt? Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the … Over geologic time, volcanic eruptions and related processes have directly and … software karafun free downloadWebVolcanoes form where the subducting oceanic plate gets hot enough to “sweat” fluids and initiate melting.
