I drew a cube for that. Later, I saw it was sort of a cube with weird corners, but it looked hard to draw. I'm not sure if they gave that to us.

its not something you would expect to see on a dynamic planet test anyways

yeah, that is not within the context of the rules anyway. That sounds like a Rocks and Minerals question.

exactly! there were a bunch of such questions, but the dynamic planet part of it was really easy. how peculiar. the regionals test was harder.

What are Rayleigh waves?

Seismic waves that travel along the surface, they are commonly called ground roll. They are normally caused by earthquakes but can also be caused by explosions and hard impacts. They can be caused in many materials but the ones caused by earthquakes are probably the only ones you need to worry about.
For more info google should be sufficent http://tinyurl.com/db7lmd

why don't you look up information on your own, this board is to help people find information that might be hard to find, and earthquake waves definitely don't fall under hard to find

In a nutshell, they're seismic waves that travel side to side on the surface. But rocketman's right, seismic waves are pretty easy to find, just Google it and youll get lots of hits.

Thanks for the advice, EASTstroudsburg13.
