Volcanic domes are associated with ___ magma.

Question

Quizplus · Accepted Answer

Volcanic domes are typically associated with felsic magma because this type of magma has a high viscosity (thickness) and doesn't flow easily. As a result, the magma tends to accumulate in a relatively small area, forming a dome-shaped mound. Felsic magma is also rich in silica and other minerals that contribute to the dome's steep sides and explosive eruption style. Mafic and basaltic magmas, on the other hand, are more fluid and tend to form shield volcanoes rather than domes.
