Effusive eruptions are NOT related to which of the following?
A)Low-viscosity magma
B)Magma rich in iron and magnesium
C)The volcanic activity in Hawaii
D)Magma with a 50-75 percent silica content,high in aluminum

Question

Quizplus · Accepted Answer

Effusive eruptions typically involve low-viscosity magma, regardless of its chemical composition. This type of eruption is often associated with the volcanic activity in Hawaii. However, magma with a high silica content (such as 50-75 percent) and high in aluminum tends to produce explosive eruptions instead of effusive eruptions. Magnesium and iron content may affect the viscosity of the magma, but they are not the main factor in determining the type of eruption.
