Editing Earthquake Cake (section)

== Why This Works ==

The earth's crust is not one solid piece, but rather is broken up into several large chunks called ''Plates''. The plates are constantly rubbing against one another, and these areas of contact are called ''Fault Lines''. There are three types of fault lines, but each one of them can result in earthquakes if there is a sudden jump in movement. A ''Strike/Slip'' fault is when two plates are sliding by each other in opposite directions. We see this with the cake when we slide one half towards us, and the other away from us. When there is a lot of movement, the land breaks and fractures as it is twisted in both directions, as we can see with the icing on the cake. A ''Normal'' fault is when the plates are pulling away from each other. In this case, the land crumbles as the rockbed below moves on without it, creating large crevices and canyons. A ''Thrust'' fault is when the plates are pushing into each other, and one of them is sliding on top of the other. This creates fractured land and rock, and is how mountain ranges are formed. Both of these cases are evident with the cakes as they are demonstrated.
