Plate tectonics
miscellaneous
rocks
earthquakes
volcanos
100
layer of earth that we are sitting on
lithosphere
100
Any deformation caused by a sustained force.
what is plastic flow
100
the complex process whereby freshly deposited loose grains of sediment are converted into rock. extra points for the vocab word which describes one of the major processes involved in this
Lithification
Cementation
100
name a transform plate boundary
san andrea fault
100
hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
what is lava
200
theory that was built upon continental drift theory
what is the theory of plate tectonics
200
name and draw at least 4 seafloor structures
continental shelf, slope, abyssal plain, hill, seamount, ocean trech, volcanic island
200
Type of Rock caused by changes due to intense heat and high pressure then recrystallizes.
what is metamorphic rock
200
most divergent plate boundaries cause these and how
what are underwater mountain ridges, expose new magma
200
which is most common cause of land volcanos?
when one plate moves under the other, convergent--subductive
300
A parallel pattern of rock material found at identical locations on each side of the Mid-Atlantic Ridge reveals rock of the same geologic age and polarity
convergent plate boundary with subduction
300
the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
what is a fossil?
300
Weathered sediments are laid down in a new location helping create new landforms or rocks
what is deposition
300
The great majority of seismicity on the planet occurs here
what is a plate boundary. bonus-- which plate mvmt causes deepest and strongest quake
300
two types of volcanic eruptions
effusive- magam flows out as lava
explosive- magma in pieces called pyroclasts
more bubbles= more explosive
400
A parallel pattern of rock material found at identical locations on each side of the Mid-Atlantic Ridge reveals rock of the same geologic age and polarity. this is proof for what?
what is sea floor spreading
400
These always cause craters and sometimes mass extinction
What are asteroid impacts?
400
what are the two types of igneous rocks
what are extrusive and intrusive
400
what are the four types of faults
normal, reverse, strike-slip, and oblique
400
rounded, steep sided mound result of magma which is hihgly viscous (resistant to flow)
what is a lava dome
500
the motion that is caused by temperature and density differences inside the earth
what is convection
500
a solid composed of one or more minerals
what is a rock
500
the most common type of intrusive igneous rock (remember that slower cooling means larger crystals)
what is granite
500
what is often used to classify/ measure an earthquake and bonus points for type of line
richter scale. logarithmic
500
columnar jointing (caused by lava cooling under stress)
