What happens during compaction?
Sediments are compacted and water is removed.
What happens during cementation?
Particles are cemented together.
How is coal made?
Made in freshwater swamps, plant material dying off faster than bacteria can break it down
Big, circular, downward bending structures.
Big, circular, upward bending structures.
What is a seismograph?
The instrument that records the passing of seismic waves.
What is a seismogram?
the record of an earthquake's seismic waves
If the hangin wall moves up what kind of fault is it?
If the hanging wall moves down with a high angle what is it?
If the hanging wall moves down with a low angle what is it?
Which of these slow mass wasting events happens in areas of permafrost?
This block of rock is bounded by normal faults and it moves up, what's it called?
Sedimentary rocks basically made up of two types of sediment: either detrital or chemical. Detrital rocks are classified primary based on what characteristic?
What affects mass wasting?
Gravity, slope angle, lubrications
The most abundant chemical sedimentary rock type is?
The process of stuff moving downslope due to gravity is called?
What type of structure are the Black Hills of South Dakota?
In areas of creep how does freezing and thawing help it?
As it freezes the water expands pushing the particles up at an angle and when it thaws, gravity pulls those particles back down which moves particles faster.
True or false? S-waves goes through all 3 phases of matter.
False. Only solids.
The small shaking after the main event is called?
The San Andreas is an example of what kind of fault?
Most rapid type of mass wasting event is a what?
Why are sedimentary rocks important?
contain fossils, show changes in geologic time, economically important.
Which is the fastest? P-waves, S-waves, or surface waves?
What is a transform fault?
There are 3 important processes that affect metamorphism. What are they?
Pressure, heat, chemically active fluids
In sedimentary rocks what are the group of rocks called that are formed from the evaporation of sea water?
What are 2 famous examples of evaporites?
Rock salt and gypsum
In earthquakes, the point below the surface where all the seismic waves start from is called?
The point on the surface of an earthquake above the focus is called?
The 3 main things that affect the amount of destruction from earthquakes?
Intensity of earthquake, design of structure, nature of surface material.
How do we know about Earths interior?
Seismic waves/ P and S-waves
What is folliation?
The parallel alignment in a metamorphic rock
What is the parent rock of marble?
What is the primary agent of contact metamorphism?
What is the primary agent of regional metamorphism?
True or False? Sedimentary rocks are the most common rocks on earths surface.
How do you find distance from epicenter?
P and S-waves difference in time.
True or False? Tsunamis are caused by a sudden displacement of large volumes of sea water.
The steepest, most stable slope angle in unconsolidated sediments is called what?
The angle of repose
What is the single most characteristic feature of sedimentary rocks?
Crack in a rock with no movement is called?
Crack in a rock with movement is called?
True or false? Most limestones are biochemical In origin.
Which of the 2 types of metamorphism, regional or contact, produces the greatest volume of metamorphic rock?
A grobin is a block of rock bounded by what kind of faults?
True or false? Metamorphism is common in mountain building.
