Minerals
These six properties are necessary for mineral classification (must name all within 10 seconds).
What is homogenous, inorganic, crystalline, specific chemical composition, solid, and naturally occurring?
This is the most common rock in the upper mantle. (Bonus - This mineral gives it its distinct color.)
What is peridotite; olivine?
This term refers to a metamorphic rock's parent (must also name a common parent rock + metamorphic pair).
What is protolith? (Limestone & Marble, Quartz & Quartzite, etc)
This ductile deformation has the oldest rocks on the outside of the fold, and the youngest rocks are on the inside.
What are synclines?
Jeroen’s native country’s flag contains these three colors arranged in this pattern (must describe flag).
What is red, white, and blue in rows?
An ordered atomic structure lends to this property, necessary for mineral classification.
What is crystalline structure?
The blue dragon lava at Craters of the Moon is primarily composed of this type of flow, referring to a ropy or fibrous texture in Hawaiian.
What is pahoehoe?
An increase in these three things can lead to the formation of a metamorphic rock.
What are temperature, pressure, and directional stress?
These are the three features of folds.
What are hinges, limbs, and axial planes?
This geologic event occurred in Amanda’s home state, possibly inspiring her love of volcanism.
What is the Mt. Saint Helens eruption?
This is the most abundant mineral group in Earth’s crust, forming this building block of the Earth’s crust and mantle (must name both).
What are silicates; the silicate tetrahedron?
An igneous rock type that contains less iron and magnesium and more silica is formed in this viscosity of magma.
What is high viscosity (felsic)?
This sedimentary rock type accumulates from remains (skeletons) of marine organisms.
What are biochemical sedimentary rocks?
This is the angle clockwise from North of an imaginary line parallel to Earth’s surface.
What is a strike?
As a member of the Marching Illini, Sam played this instrument that shares similarities with low-frequency sound waves traveling through a volcano.
What is a trombone?
When sodium and chlorine react, the sodium atom loses one electron, and the chlorine gains it. This type of bond is formed, creating this mineral (must name both).
What is ionic; halite?
This is the primary rock texture that comprises Yellowstone.
What is pyroclastic?
This Sedimentary classification has angular clasts in a fine-grained matrix.
What is Breccia?
This remaining piece of the Farallon plate caused volcanic formation in North America.
What is the Juan de Fuca plate?
While researching this mountain range formed by active convergent plate boundaries, Jamie was forced into political activism to secure safe passage.
What are the Himalayas?
These types of minerals are commonly identified when hydrochloric acid releases carbon dioxide on their surface.
What are carbonates? (In the field, we’ve seen dolomite, calcite, malachite, and azurite.)
This rock, common in subduction zones, was abundant in this pre-caldera Yellowstone feature (must name both rock and feature).
What is andesite at Mt. Washburn?
This is the order of metamorphic grade from low grade to high grade.
What is slate, phyllite, schist, and gneiss?
The Rocky Mountains were primarily formed during this orogeny (must say time).
What is the Laramide Orogeny (70-40 Ma)?
This is Sydney’s favorite app, popular among geologists and geographers alike.
What is Google Earth?
