Quizplus · Accepted Answer

The low-viscosity, fluid lava of hot-spot volcanoes is typically mafic, which means it has a low silica content and is rich in magnesium and iron. This type of lava flows easily and can travel long distances before solidifying. Felsic and intermediate lava are more viscous and tend to form explosive eruptions, whereas ultramafic lava is much less common and typically only found in specific tectonic settings.
