3 rock types
What is sed, ig, meta
100
These are the layers of the earth by composition
What is crust, mantle, and core
100
These are 3 out of 4 volcanoes that resemble hills
What is scoria, shield, composite, dome
100
These joints often form through cooling and contraction of a recent lava
What is columnar joints
100
This may result when earthquakes shake the subsurface and the grains become rearranged, leading to excess pore water released
What is Liquefaction
200
This describes the time it takes for half of the parent atoms to decay into daughter atoms
What is half life
200
Thesea are the layers of the earth by strength
What is asthenosphere and lithosphere
200
This controls how explosive an eruption may be
What is viscosity (controlled by composition) and gas content
200
This is a fault that results from tension
What is normal fault
200
These are two types of earthquake waves
What is P, S or surface (love/rayleigh)
300
This rock type can be metamorphosed
What is all of them can
300
Oceanic crust is (thicker or thinner) and (less dense or more dense) than continental crust
What is thinner and less dense
300
This is another word for volcanic mudflow, which often occur on compositive volcanoes (starts with L)
What is lahar
300
This is a break in a rock without displacement
What is joint
300
This is the location on the surface of the Earth where an earthquake occurs
What is epicenter
400
What does a vesicular texture indicate?
What is there was a high gas content
400
This was why continental drift was rejected
What is a lack of mechanism
400
This is a broad and low volcano composed of basaltic lava flows
What is shield volcano
400
This type of stress often results in folds
What is differential
400
Sudden movement on a fault that raises or drops the seafloor may result in this devastating event
What is tsunami
500
This is the difference between breccia and conglomerate
What is shape of clasts
500
This is why mid-ocean ridges are higher than surrounding oceanic crust
What is they are hotter and the lithosphere is thinner
500
This forms when basalt lava flows reach the water
What is pillow basalt
500
These are the three differential stresses
What is compression, tension and shear
500
This is how many earthquakes occur annually that are magnitude 8 or larger
What is around 1
