Q: Answer the following question given this paragraph: The exact cause of supervolcano eruptions is still debated. However, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion. This creates a caldera into which the surface collapses ( Figure below ). The composition of the eruption is felsic or highly felsic. Q: What kind of eruption do scientists think is caused by a very large magma chamber erupting entirely in one catastrophic explosion? Choices: - brucei eruption - mangxamba eruption - supermagma eruption - supervolcano eruption A:
A: supervolcano eruption
