eruptions?
A The more gas magma contains, the more explosive a volcanic eruption will be.
B

As gas builds up in magma, volcanic eruptions occur once in the magma chamber
and once above ground
Gas found in magma determines only the intensity of eruptions involving
composite volcanoes and not shield volcanoes.
D
