As Magma Approaches the Surface,water Contributes to the Explosive Potential

question 15

Multiple Choice

As magma approaches the surface,water contributes to the explosive potential of the eruption because ________.

• A)water has a large heat capacity,which allow it to keep the magma hot enough to explode
• B)water dissociates to hydrogen and oxygen at high temperatures but reacts violently at decreasing pressures to produce explosive eruptions
• C)water has a lower density in its solid phase than its liquid phase which makes it explode when pressure decreases
• D)water dissolved in magma flashes to steam as pressure decreases,and the volume increase leads to an explosive potential
