What mineral is this?
This mineral has two cleavages at ~90°, H=6, and is a major component of the crust
What is feldspar?
This metamorphic rock has a shiny and flaky look because of mica
What is schist?
This boundary has shallow earthquakes, produces lots of basalt and gabbro, and has normal faulting
What is a mid-ocean ridge?
These two deformational features look like smiles and frowns and result from ductile deformation
What are anticlines and synclines?
This mineral has conchoidal fracture, lots of Mg, and commonly occurs in basalt
What is olivine?
This calcium-rich rock is made of zillions of microscopic shells from plankton
What is limestone?
This boundary has shallow earthquakes, basaltic eruptions, and normal faulting, and occurs today in Eastern Africa
What is continental drift?
This type of faulting results from sudden fracturing and slippage of rocks undergoing compressional stress
What are reverse/thrust faults?
This ore mineral can be black or red or silver, but its streak is always brick red
What is hematite?
This rock is the volcanic equivalent of granite
What is rhyolite?
This boundary has shallow to very deep earthquakes and eruptions of a rock named after a South American mountain chain
This most common form of rock deformation results from brittle fracturing of crustal rocks without differential stress
What are joints?
This mineral has lots of calcium, forms in drying lakes and shallow seas, and is a component of sheet rock/wall board
What is gypsum?
This rock is the intrusive equivalent of basalt
What is gabbro?
This boundary type has earthquakes and is responsible for creating the tallest mountains on Earth
What is a continental collision?
This type of faulting results from sudden fracturing and slippage of rocks undergoing tensional stress
What are normal faults?
This mineral has one perfect cleavage, little or no color, and was once used to make oven windows
What is muscovite?
You get this rock from metamorphosis of limestone
What is marble?
This boundary has earthquakes, but no magmatism
What is a transform/strike-slip boundary?
Enormous masses of rock with “tight folds” or “isoclinal folds” are most likely to be created at this plate boundary type
What is a continental collision?
