21. Quiz Answers – use to check your understanding – DO NOT CHEAT!B
Pangaea
Mid-ocean ridges, deep ocean trenches
About 2 inches
Since most earthquakes are caused by plates squeezing together, and volcanoes are caused by plates moving apart, the locations of these tell us where the edges of the plates are located.
