Download 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.

the Earth subsystem that it most closely
influences. Note: Some may be used more than
once.
