Plate Tectonics Test

TriviaHow well do you know your

stuff?

What is the dark colored rock that makes up much of the ocean

floor?

Basalt

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 _____________.

Inner Core

When molten material reaches the surface of

Earth, it is called __________.

Lava

_________ is a stress that pushes rock in 2 opposite directions.

Shearing

What type of geologic

event can occur at the San Andreas

Fault in California?

Earthquakes

Two continental plates that crunch or smash together slowly can

produce ___.

Mountains

Which layer of Earth is made of liquid nickel &

iron and moves to create Earth’s magnetic field?

Outer Core

Molten material inside Earth is called _______.

Magma

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?

Conduction

The single landmass that broke apart millions of

years ago is called ___________.

Pangaea

What is the stress that pulls on the crust where two plates are moving

apart?

Tension

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)

Radiation

____ are waves of energy that move through Earth

generated by earthquakes. Geologists use these to

study about Earth’s interior.

Seismic Waves

A____ fault describes the way rock breaks at

transform boundaries. This break results from the stress of shearing.

Strike-Slip

Multiple Choice:The ______ heats the mantle and makes the convection currents move.A. sunB. coreC. geothermal activity

The CORE!

What kind of stress pulls on the plates at divergent

boundaries?

Tension

What kind of fault results from converging plates?

Reverse

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.
