Chapter 5 and 6 Test Study Guide
... Geologists cannot be certain about the type of eruption or how powerful it will be but they can monitor earthquakes occurring around a volcano to predict possible eruptions. Magma moving upwards will trigger small quakes. (p 228) 9. Explain how a hot spot in the ocean floor can gradually form a seri ...
