Transcript Use the following list to match to the statements below: Seismic

1. What dense magnetic material is the Earth’s core
mostly made of?
ANS: Iron
2. Because the crustal rocks contain specimens
manufactured within the mantle (volcanic in nature),
as well as sedimentary rocks formed at the surface,
the ____________, or the solid outer portion of the
Earth is very heterogeneous
ANS: Lithosphere
3. The cooler portion of the mantle which is in contact
with the crust is known as the _____________.
ANS: Asthenosphere
4. ______________ ______________ in the
asthenosphere help to drive the tectonic plates on
the Earth’s surface.
ANS: Convection Currents
5. Tectonic plate boundaries that move apart from one
another, are known as ____________________.
ANS: Divergent
6. Tectonic plate boundaries that subduct, or meet
and one is forced beneath another, are known as
________________ plate boundaries.
ANS: Convergent
7. Highly active earthquake zones form where
tectonic plates slip past one another. This type of
tectonic boundary is known as
________________.
ANS: Transform
8. Where does the energy that moves tectonic plates
around come from, and by what process is this
energy generated?
ANS: Convection currents within the mantle that
are formed due to the heat of fission of
radioactive elements found within the Earth.
Match the following energy transferal methods to
the Earth subsystem that it most closely
influences. Note: Some may be used more than
once.
Conduction
Convection
9. Lithosphere
ANS: Conduction
10. Hydrosphere
ANS: Convection
11. Biosphere
ANS: Conduction
12. Atmosphere
ANS: Radiation; Convection
Radiation
Use the following words, and match to the
statements:
Ultraviolet
Infrared
Cosmic
13. Type of energy transferred from the solid
surface of the Earth, back out into the
atmosphere.
ANS: Infrared
14. Type of energy trapped in the VanAllen Belt
ANS: Cosmic
15. Long-wave radiation, mostly felt as thermal
energy
ANS: Infrared
16. Energy mostly responsible for greenhouse
effect. ANS: Infrared
Match the letters in the diagram below to the
statements below.
17. May transfer energy through convection and
radiation equally efficiently
Ans: A
18. On the Earth, you
would weigh less here
ANS: F
F
H
19. Represents the
mantle
ANS: E
20. Represents the asthenosphere
ANS: D
21. Represents the lithosphere H
G
22. Earth’s magnetic field is created largely from this
effect. Convection currents within the liquid outer core,
cause the solid inner core to spin faster than the Earth.
ANS: Dynamo effect

evidence
24. Xenoliths and ophiolites are these
ANS: Direct evidence
