We just learned about the Mercalli Intensity Scale.

Another interesting thing about earthquakes is Seismite.

This is a type of rock formed when an earthquake causes a bunch of sedimentary layered rocks to get messed up and deformed.

Sedimentary rocks usually look like a bunch of sideways lines stacked on top of each other.
Sometimes when an earthquake happens, the lines get squished around and sometimes look like bubbled up rocks.

That squished up rock is called seismite.
