ESS 101 Midterm UW EXAM QUESTIONS
WITH ANSWERS
What mineral group is a major economic source of lead? -
CORRECT ANSWERS ✔✔sulfide
The _____ mineral group is a major economic source lime
for cement. - CORRECT ANSWERS ✔✔carbonate
Meteorites that strike the earth are predominantly
composed of _____? - CORRECT ANSWERS ✔✔iron-nickel
and silicate minerals
Why are P-waves completely absorbed as they enter the
outer core? - CORRECT ANSWERS ✔✔none of the above
answers are correct as P-waves are not completely
absorbed in the outer core
During differentiation of the earth, heat was generated
from _____. - CORRECT ANSWERS ✔✔1) kinetic energy of
impacting planetesimals
2) compressional heating during condensation of
planetesimals
3) radioactive heating
, Why does the Yellowstone hotspot volcanism produce
more explosive volcanic eruptions than the Hawaiian
hotspot volcanism? - CORRECT ANSWERS ✔✔upwelling
basaltic magma partially melts the overlying continental
crust producing viscous rhyolitic lava
Which of the following bond strength rankings are in the
correct order from weakest to strongest? - CORRECT
ANSWERS ✔✔Van der Waal, ionic, covalent
How can we best explain the fact that the inner and outer
cores are both composed of metallic iron (Fe) and nickel
(Ni) yet the outer core is liquid and the inner core solid? -
CORRECT ANSWERS ✔✔the melting temperature for Fe-Ni
is lower than the geothermal gradient temperature in the
outer core
What type of seismic wave shadow zone is shown on the
image above? - CORRECT ANSWERS ✔✔S-wave
How can one best explain the seismic wave properties
shown in the above diagram? - CORRECT ANSWERS ✔✔1)
refraction of seismic wave due to density changes
2) absorption of seismic waves due to phase change from
solid to liquid
