GeoJeopardy! Fridays

Time for GeoJeopardy! Fridays, because my first PhD exam is today, oh boy. Some of these seem to be a little bit harder than normal.

- Geology -

A deep ravine that's often dry in the summer, it shares its name with a "grand" dam in Washington state


 This layer of rock between the earth's core & crust makes up about 85 percent of the planet's mass


From the Greek for "without shape", this term refers to rocks & minerals that have no crystalline structure


Lamina is a layer in this type of rock that is less than 1 cm. in thickness & is visually separable from other layers


"Bovine" term for a crescent-shaped lake formed in an abandoned river bend
