WebThe magma rises and collects in chambers within the crust. As magma fills the chamber, pressure grows. If the pressure gets high enough, the magma can break through the crust … WebThis forms magma (molten rock). The magma rises and collects in chambers within the crust. As magma fills the chamber, pressure grows. If the pressure gets high enough, the magma can break through the crust and spew out in a volcanic eruption. Most explosive volcanoes occur above subduction zones.
WebThis causes some of the rocks to melt. The melted rock, or magma, is lighter than the surrounding rock and rises up. This magma collects in magma chambers, but it is still miles below the surface. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions. WebVolcanic eruptions and earthquakes are more tangible, but their cause is rooted in the theory of plate tectonics, a concept not taught until the middle school years. ... The levels of silica and dissolved gases in the magma determine whether a volcano erupts explosively or effusively. Magma and gas may escape through cracks and weak areas on ...
