1
What is the relationship between mountain building, volcanoes, and earthquakes?
Mostly occur @ plate boundaries & generated by plate motion from convection
Mostly occur at plate boundaries & from eruptions on land due to convection
Mostly occur in oceans and center of plates on land because of convection
Mostly occur in oceans & change the seafloor by spreading apart making rock
2
Jo creates a poster of sea-floor spreading, mid-ocean ridges > ocean trenches. Which best describes the rocks age order?
Poster begins with the youngest rock and ends with the oldest
Poster shows different stages of rock whose relative age cant be determined
Poster begins with the oldest rock and ends with the youngest
All the rock stages shown on the poster are the same age
3

stress
shearing
5
Mountains result from which type of plate boundary?
divergent
transform
convergent
strike-slip fault
6
Tevin was flying over mountains looked like waves. What is the pattern of tall mountains and low valleys called?
Anticlines=tall mountains & synclines=low valleys in a random pattern
Synclines=tall mountains & anticlines=low valleys in a wave like pattern
Anticlines=tall mountains & synclines=low valleys in a wave like pattern
Synclines=tall mountains & anticlines=low valleys in a random pattern
7
What is the mechanism by which tectonic plate motions are driven?
ocean currents
convection currents
deposition
erosion
8
Earthquakes typically result from which type of plate boundary?
convergent
divergent
transform
strike-slip fault
9
What is the cause of sea-floor spreading?
ocean floor sedimentation over millions of years that adds sedimentary rock
plate of dense oceanic crust sinks below a less dense plate of continental
development of deep water ocean trenches with magma from Earth's crust
flow of magma thru cracks in the crust that makes strips of new rock
10
The type of stress that pulls on and thins an area of Earth's crust is called?
tension
torsion
shearing
diverging
11
Rift valleys that are growing would result from which type of plate boundary?
transform
strike-slip fault
convergent
divergent
12
How do fossils provide evidence of continental drift?
The fossils show a record of climate change
The same fossils were found on land and under the ocean
Similar fossils are found all over the world
The same fossils were found on different continents
13
Which of the following statements about mid-ocean ridges is true?
They help dispute the theory of plate tectonics
They are the source of the material that forms the new ocean floor
They are major subduction zones
They occur where the oceanic crust is the most dense
14
Hawaii is a volcanic island chain. Which best describes the location of the Hawaiian islands?
subduction zone
normal fault
hot spot
convergent boundary
15
Alfred Wegner hypothesized of continental drift. Which of the following contained clues that led him to his hypothesis?
land features, fossils, and sea-floor spreading
land features, fossils, and climate
mid-ocean ridges, fossils, and weather
mid-ocean ridges, fossils, and climate
16
What determines how the plates interact at their boundaries?
the kind of plates they are and whether they keep moving
the materials the plates are made of
the difference in thickness of the plates
the kind of boundary and the directions in which the plates are moving
17
What are the three types of boundaries?
rift, trench, and convergent
divergent, convergent, and transform
divergent, convergent, and plate
tectonic, convergent, and divergent
18
The slow, steady flow of magma can form shield volcanoes some places. What's 1 cause for formation of a shield volcano?
caldera
lava plateau
earthquake
hotspot
19
How do mountains and valleys develop from a series of normal faults?
Compression folds and bends rock in the middle of a plate
Footwall slips down to form a valley at converging plate boundary
Hanging wall slips down at diverging plate boundary
Walls of rock grind past in opposite directions, pushing one side up
20
An earthquake occurs along a fault when?
Energy in the rock along the fault doesn't change for a long period of time
Enough energy builds up in rock along the fault causing it to slip or break
Stress in the rock along the fault causes magma to rise up trough the fault
Energy in the rock along the fault is changed to heat
