Which of the following best describes the relationship between gas and volcanic eruptions?
A The more gas magma contains, the more explosive a volcanic eruption will be.
B
The presence of gas in magma decreases the likelihood of a volcanic eruption.
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
