Document Summary
Volcanoes: are dramatic geomorphic agents, associated effects stretch far beyond the volcanic boundaries, and occur in very short timescales. They are the physical links between deep processes in the planet and the construction of the features of the planet (e. g. earth"s surface) --> this link is critical, because it is what sets earth apart from other planets. Part of the geophysical earth engine that drives short-term weather. Volcanic eruptions --> pose serious health and safety risks (e. g. lava, pyroclastic flows) Plume --> affects the rate at which precipitation develops, also the global climate. Just like a water jet, shoots up into the air with a lot of kinetic energy. The ash from an eruption may fall out, causing affects on humans and the surrounding environment. Style and magma composition is linked to tectonic study --> which would also drive regional hydrology. There is lightening around a volcanic eruption as when electrically charged items are thrown up into the atmosphere.
