WebSep 30, 2024 · Magma is an extremely hot liquid and semi-liquid rock found beneath the Earth's surface. The inner core, outer core, mantle, and crust make up Earth's layered structure. Magma makes up a large portion of the planet's mantle. This magma has the potential to push through holes or cracks in the crust, resulting in a volcanic eruption. WebTypes of Magma Types of magma are determined by chemical composition of the magma. Three general types are recognized: Basaltic magma-- SiO 2 45-55 wt%, high in Fe, Mg, Ca, low ... High viscosity andesitic and rhyolitic lava flows, because they can’t flow very easily, form thick stubby flows that don’t move far from the vent.
