Question

Quizplus · Accepted Answer

Effusive eruptions are typically associated with low-viscosity magma that flows easily to the Earth's surface. The magma is usually rich in iron and magnesium, but not necessarily high in aluminum or silica content. The volcanic activity in Hawaii is known for its effusive eruptions, but this is not a defining characteristic of such eruptions.
