Volcanism; products and processes
Volcanoes and volcanic eruptions always capture the imagination, so long as one is at a safe distance from the action. These processes have been instrumental in shaping Earth – physical and human landscapes and ancient migration routes, the origin and shaping of life, climate, plus all those subterranean processes deep in Earth’s crust and mantle. Volcanic rocks provide a window into our ancient world and worlds beyond our own. Observing volcanism in action tells us which window to open.
