5 Matching Questions

1. dome volcano
2. dormant volcano
3. caldera
4. secondary effect
5. cinder volcano

1. a (geology) earthquake effects that result when ground movement causes other types of damage, such as landslides, flooding caused by subsidence of land, tsunamis, liquefaction and fire
2. b thick lava flows; dome shaped mountain
3. c a steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano's opening
4. d a volcano that has not erupted for a long time, but may erupt again one day

5 True/False Questions

1. strato volcano (composite volcano) → conical, steep-side, symmetrical volcano (ratio of height to breadth relatively large) composed of alternating layers of silicic lavas and pyroclastics. Typical of subduction zone volcanism.

   True        False

2. primary effect → (geology) permanent features produced by earthquake, such as fault scarps, surface ruptures, and offsets of natural or human-constructed objects

   True        False

3. conduit → a fissure in the earth's crust (or in the surface of some other planet) through which molten lava and gases erupt

   True        False

4. focus → the point along a fault at which the first motion of an earthquake occurs

   True        False

5. Richter scale → A low, steep-sided cone of spatter built up on a fissure or vent

   True        False
