EAPS 106 Exam 1 review
Why earthquakes are felt farther away in the eastern US
compared to the western US - ✔ ✔ The crust is more
broken up in the west
because it is a plate boundary.
Why is the interior of the earth layered - ✔ ✔ Planetary
accretion
Why is the outer core a liquid? - ✔ ✔ It is the only layer with
a temperature higher than its melting temperature.
Why Italy recently sent seismologist to jail - ✔ ✔ for not
predicting the 2009 M6.3 L'Aquila earthquake based on
foreshocks.
Why the US Geological Survey believes there is a high seismic
hazard in the midwest - ✔ ✔ New Madrid Seismic zone
How did the earth acquire its internal heat? - ✔ ✔ Heat of
collisions plus
radioactive decay leads
, new planets to be molten
(melted) inside, which leads
to differentiation as heavier
elements sink to form a core
and lighter elements rise to
form a crust and mantle
How do the plates deform before compared to during a
subduction zone earthquake - ✔ ✔ subduction of the
Pacific Plate was pushing
Components required for earth's magnetic field - ✔ ✔
Convection in the outer core combined with the spin of the
planet, liquid iron as coils and then attracts more liquid iron
Evidence that Wegner used to suggest continental drift - ✔ ✔
North and south america coastlines fit with Europe and
Africa/identical volcanic flows appear on both sides of the
Atlantic/fossils of non-swimmers found on both sides of the
Atlantic
How an earthquake early warning system works - ✔ ✔
Seismic waves travel slower than the speed of light.
Therefore, one can detect an earthquake and
