Which method is NOT used to
study the Earth’s interior?
A. Analysis of the Earth’s magnetic field.
B. Analysis of seismic waves from
earthquakes.
C. Analysis of lava.
D. Analysis of samples collected from the
drill hole that extends to the outer core.
The asthenosphere is interesting
because…
A.
B.
C.
D.
It creates the magnetic field.
It is the source of Earth’s heat.
It is a solid with liquid properties.
It consists of 13 tectonic plates.
Why does density increase as you
move towards the center of the Earth?
A. It doesn’t, it decreases.
B. The sun’s radiation causes Earth’s
layers to compact.
C. Because temperature increases.
D. Early in Earth’s history, denser
elements sank towards the center.
The core of the Earth is hotter than
the crust because…
A. The crust has cooled over time.
B. The core is generating heat from
radioactive decay of some elements.
C. The original heat generated from
Earth’s formation is still in the core.
D. All of the above.
The Earth’s magnetic field is
generated in which layer?
A.
B.
C.
D.
The lithosphere

The outer core
The asthenosphere
The Earth’s magnetosphere
protects us from what?
A.
B.
C.
D.
Greenhouse gases.
Solar particles.
Earthquakes.
Asteroids.
Which of the following is NOT
true about Earth’s magnetic
field?
A. It is a temporary magnet.
B. It is an electromagnet.
C. It extends beyond the Earth’s
crust.
D. It is a permanent magnet.
What is NOT true about the Northern
and Southern Lights?
A. They are created by meteorites
burning up in the atmosphere.
B. They occur at the magnetic poles
of the Earth.
C. They are created when solar
particles trapped in Earth’s magnetic
field collide with air.
What effect does the Sun have on
Earth’s magnetic field?
A. The Sun does not affect the Earth’s
magnetic field.
B. The Sun’s radiation makes the
magnetic field hot.
C. Solar winds distort the Earth’s
magnetic field.
D. The Sun’s magnetic field holds the
Earth in its orbit.
Convection is responsible for what
process on Earth?
A.
B.
C.
D.
Plate tectonics
Ozone depletion
Magnetism
Global warming
Convection currents rely on
differences in:
A.
B.

D.
Pressure
Temperature
Phase
Depth
In which layer of the Earth does the
convection that drives plate tectonics
occur?
A. The asthenosphere
B. The inner core
C. The lithosphere
D. The outer core
What drives convection in the
asthenosphere?
A. Temperature differences between the cooler
lithosphere and warmer lower mantle
B. Pressure differences between the lithosphere
and lower mantle
C. Temperature differences between the cooler
lower mantle and warmer lithosphere
D. Compositional differences between the
lower mantle and lithosphere
When liquids and gasses become
hotter than the surrounding matter,
they …
A.
B.
C.
D.
turn into solids and stop moving
becomes less dense and rise
give off visible light
become more dense and sink
Could the Earth ever lose it’s
magnetic field?
A. No, the magnetic field never
really changes.
B. Yes, when the magnetic field
reverses.
In what way did your electromagnet
model NOT represent the Earth’s
magnetic field?
A. nail = inner core
B. battery = sun
C. coiled wire = outer core
Why is the Earth’s magnetic
field invisible?
A. It does not produce wavelengths in
the visible spectrum.
B. Because the visible light produced
is traveling too fast.
C. Because only heat energy is
produced.
D. The magnetic lines ARE visible
with special equipment.
Why do gases on the Sun follow the
Sun’s magnetic lines and why can you
see them?
A. The gases are very hot and are
attracted to magnetic fields.
B.The gases become charged and
excited and get caught in the
magnetic field.
C. Because they are made of iron and
become magnetized.
Could we breathe if we lost our
magnetic field?
A. Yes, we would still have our
atmosphere.
B. No, the solar winds would strip
our atmosphere away.
C. Scientists don’t really know the
answer.
