When You Open a Bottle of Soda Slowly It Tends

Multiple Choice

When you open a bottle of soda slowly it tends not to spill, whereas if you open it too rapidly, you may get a wet hand. What parallel is there with effusive versus explosive eruptions?

A) Effusive eruptions are like the slowly opened bottle. The air in such eruptions is released so it cannot build up in the magma, thus keeping the eruption non- violent.
B) Explosive eruptions are like the rapidly opened bottle. Because the gases in the magma are released all at once, the eruption is not violent.
C) Effusive eruptions are like the rapidly opened bottle. Because the gases in the magma are released all at once, the eruption is not violent.
D) Explosive eruptions are like the slowly opened bottle. The air in such eruptions is released so it cannot build up in the magma, thus keeping the eruption non- violent.
