Plate Tectonics Test
TriviaHow well do you know your
stuff?
What is the dark colored rock that makes up much of the ocean
floor?
What is the cycle that slowly moves the soft
rock in the mantle, transferring heat, and
moving the plates around on Earth?
Convection Currents
True or False?
Volcanoes may form along convergent
boundaries.
TRUE…at Subduction Zones
The layer of Earth that is described as a dense,
metal ball is the _____________.
When molten material reaches the surface of
Earth, it is called __________.
_________ is a stress that pushes rock in 2 opposite directions.
What type of geologic
event can occur at the San Andreas
Fault in California?
Two continental plates that crunch or smash together slowly can
produce ___.
Which layer of Earth is made of liquid nickel &
iron and moves to create Earth’s magnetic field?
Molten material inside Earth is called _______.
Wegener’s hypothesis of _________________
states that the continents were once joined
together.
Continental Drift
What is the type of heat transfer where a metal spoon heats up if its left
in a hot pot of soup?
The single landmass that broke apart millions of
years ago is called ___________.
What is the stress that pulls on the crust where two plates are moving
apart?
The heat you feel when you stand in front of a fire is an example of
which form of heat transfer? (Hint: Energy transfer through space in the form
of rays or waves)
____ are waves of energy that move through Earth
generated by earthquakes. Geologists use these to
study about Earth’s interior.
A____ fault describes the way rock breaks at
transform boundaries. This break results from the stress of shearing.
Multiple Choice:The ______ heats the mantle and makes the convection currents move.A. sunB. coreC. geothermal activity
What kind of stress pulls on the plates at divergent
boundaries?
What kind of fault results from converging plates?
What are 3 geologic events/formation that
happen on Earth due to plate tectonics?
Earthquakes,Volcanoes,Mountain Building
Which type of plate boundary would you find at letter X?
Divergent
Name and describe the process that is happening at letter X.
Seafloor SpreadingAs plates pull apart at a divergent boundary, magma come up through a crack hardens and forms new seafloor.
Name and describe the process that is happening at letter Z.
Subduction
As plates come together at a convergent boundary, the denser oceanic plate sinks under (sub=under) the less dense plate.
Which letter in the picture identifies the area showing
continental crust?
C; Continental
True or False?
If convection currents stopped moving it would
mean that the inner core is no longer heating the
mantle.
TRUE!The heat from the inner
core heats the mantle. The movement in the mantle
make the plates of the lithosphere move slowly.
