WebVolcanoes are an opening of the Earth's crust through which molten rock, gases and ash can escape. This mixture of materials is called magma while it's underground, lava when it is erupted and igneous rock once it's cooled and solidified on the surface. According to the theory of plate tectonics, Earth's lithosphere, its rigid outer shell, is broken into sixteen larger and several smaller plates. These are in slow motion, due to convection in the underlying ductile mantle, and most volcanic activity on Earth takes place along plate boundaries, where plates are converging (and lithosphere is being destroyed) or are diverging (and new lithosphere is being created). leadership companion adf
