According to this map, at what
geological feature do must volcanoes
occur?
Plate boundaries
The best evidence that two land areas
were once connected is the discovery
that both land masses
A. are in the same stage of succession.
B. have similar types of rocks and fossils.
C. have the same climate.
D. exist along the same line of longitude.
have similar types
of rocks and fossils.
Scientists claim that the continents of South America and
Africa were once a single landmass. All of the following
observations support this claim except
A.
B.
C.
D.
the mountains on these continents have similar rocks of the same age.
similar fish live in the ocean off the coasts of these continents.
these continents appear to fit together like a puzzle
the same kinds of fossils have been found on these continents.
similar fish live in the
ocean off the coasts of
these continents.
Sea floor magnetic stripes on the Pacific sea
floor tend to be wider than equivalent-age
magnetic stripes on the Atlantic sea floor.
This suggests that:
A. the Pacific Ocean is older than the Atlantic Ocean.
B. the Pacific Ocean is younger than the Atlantic Ocean
C. spreading rates in the Atlantic Ocean are slower than
in the Pacific Ocean.
D. Spreading rates in the Pacific Ocean are slower than
in the Atlantic Ocean.
spreading rates in
the Atlantic Ocean
are slower than in
the Pacific Ocean.
All of the following help to drive
plate tectonic movement except:
A. convection in the Low Velocity Zone
B. the weight of descending ocean plate in
subduction zones
C. mountain building at continent-continent
collision zones
D. cooling of new lithosphere along the slopes
of sea floor ridges
mountain building at
continent-continent
collision zones
There are 12 major tectonic plates that make up
the earth’s surface. There are 3 major types of
plate boundaries, name 1.
Convergent
Divergent
transform
Compare the
densities and
thickness of
oceanic and
continental crust
Oceanic – thinner,
more dense
Continental- thicker,
less dense
a).
b).
c).
d).
Which graph
represents
temperatures
inside the earth?
a).
b).
c).
d).
B – gets
hotter as
get closer
to core
Which is accurate based
on surface features?
1- convection cells pulling
ridge apart
Which table best shows the relative densities of the
crustal bedrock at locations A-D?
2! – B and C are oceanic crust
(more dense), A and D or
continental crust (less dense)
The oldest rocks would have
come from which sample site?
1 – farthest from ridge
where originates
What happens at
convergent plate
boundaries?
Plates collide, come
together
Where would the hottest
crustal temps be found?
C! – where magma comes
out!
Which graph correctly shows
relative age of bedrock?
4! – Shows B is older than C
The probable source of the Earth's
magnetic field is:
A. plate motions
B. sunspot activity
C. convection in the outer core
D. sea-floor magnetic reversals
The probable source of the Earth's
magnetic field is:
A. plate motions
B. sunspot activity
C. convection in the outer core
D. sea-floor magnetic reversals
Make your wager
1. List three pieces of evidence
of plate tectonics
2. List two surface features we
see on Earth as a result
Evidence
• Paleomagnetism
• Sea floor spreading
• Fossil evidence
• Continents fit like puzzle
• climate
Changes in earth’s features
• Volcanoes
• Mountains
• Earthquakes
• Tsunamis
• Trenches
