Magmatic and Volcanic Processes in the Earth Poster

Magma from the planet's mantle rises through the planet's crust, if the magma from the mantle reaches the planet's surface it behaves differently depending on the viscosity of the molten constituent rock. Viscous (thick) magma produces volcanoes characterised by explosive eruptions, while non viscous (runny) magma produce volcanoes characterised by an effusive eruptions pouring large amounts of Lava onto the surface.
