Plate Tectonics

The Ring of Fire (Pacific Ring of Fire) is an area of Pacific Plate subduction, rimming (of course) the Pacific Ocean. The plate subduction creates a line of volcanism geographically around its perimeter that appears to form a circle or ring.

The Ring of Fire is the subducting plate boundary of the shrinking Pacific Ocean. The subducting oceanic crust is being drawn under less dense oceanic and continental crust and is melting into the upper mantle which can lead to volcanism and earthquakes.

Mid ocean ridges are the direct result of sea floor spreading.

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.
