GeoJeopardy! Fridays #63

Time for GeoJeopardy! Fridays, because it's time for a break.

The University of Wisconsin-Madison Geology Museum has the state rock of Wisconsin; not to be confused with the state rock of New Hampshire, it's the red type of this


Formed by magma, this one of the 3 major types of rock may be plutonic, or formed deep in the Earth


 A schism is a division into faction; this type of rock, one letter different from "schism", has distinct layers
