A geographical example of a transform fault boundary is the San Andreas fault. Another example of a fall boundary is the Northridge fault.

Slabs of ocean floor return to the mantle in subduction zones

P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval. 

Many plutons clump together as they rise through the crust.
