  1. andesitic magma - magma that is a mix of basaltic and rhyolitic; eruption may or may not be explosive
  2. basaltic magma - magma that has low viscosity and low silica and gas content; eruption is non-explosive
  3. cinder cone volcano - volcano formed of volcanic rock and ash; erodes quickly
  4. composite volcano - volcano that is tall and steep; formed of lava and volcanic debris
  5. Hawaiian eruption - non-explosive or very mild volcanic eruption
  6. hot spot - an active area of volcanoes due to a consistent source of magma in the asthenosphere
