WebMay 6, 2024 · Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. This Volcanoes 101 video from National Geographic discusses where volcanoes are found and what their properties come from: WebIn the Earth's crust the magma is at a higher pressure than at the Earth's surface, so it is possible for gases (water vapour and carbon dioxide) to be dissolved in it. As lava moves up towards the Earth's surface, the gas tries to escape because the pressure on it is decreasing. Think about what happens when you shake a bottle of soda! WebLocation. Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate. The magma rises through the mantle, and erupts to form great composite volcanoes such as Vesuvius. rwj barnabas health benefits
