					  Focus					 
					 What is the term for the point underground where movement begins in a earthquake? | 
					  Triangulation					 
					 You can find the location of an earthquake by plotting its distance from 3 points.  What is this process called? | 
| 
					  Ash					 
					 What is the smallest, finest kind of pyroclastic material? | 
					  Andesitic

					  Aftershock					 
					 What is the term for a small earthquake that happens after the main quake? | 
					  Primary wave or P-wave					 
					 What kind of body wave will arrive first at an earthquake monitoring station? | 
| 
					  Pyroclastic Flow					 
					 What is the term for a superhot avalanche of ash, rock, and gases? | 
					  It has a lot of water in it					 
					 Why does subducting oceanic crust melt into magma so easily? | 
					  Lots...					 
					 Name 1 volcano on earth that has erupted in recorded human history. | 
					  An oceanic plate snaps upward, and pushes a mass of water with it					 
					 Briefly explain how a tsumani happens. | 
					  Station 1					 
					 At station 1, the P-wave and S-wave arrive 3 minutes apart.  At station 2, the P-wave and S-wave arrive 5 minutes apart.  Which station was closer to the earthquake? | 
| 
					  Blocks are solid when ejected from a volcano, bombs are semi-molten					 
					 What is the difference between a block and a bomb? | 
					  Divergent Boundaries					 
					 Where does a pressure release on the mantle allow magma to easily form? | 
					  The rim of the Pacific Ocean, which is ringed by subduction zones and volcanoes
